2022年2月9日 樟之細路 出雲古道 金童山/玉女山 Laknus Seilu Trail: Crude oil well and over a pass of Chuyun historic trail to a town of strawberries

アジア最古の原油やぐら出磺坑油井, Oldest oil rig in the entire Asia at Chuhuangkeng 

先月下旬に二日がかりで歩いた樟之細路は、時間的な理由で予定していた出雲古道を歩けなかった。今回の山行は、出雲古道を歩き、その近くの山峰を登った。下った先の大湖は、イチゴで有名な町だ。1950年代末から試みが始まりその後90年代には広く知られるようになった。今は畑のほとんどがイチゴのように見える。大湖の街は、19世紀の半ば客家人による開拓が始まった。初期はタイヤル族との衝突が起きている。先月歩いた老官道は、原住民との境界である隘勇線がその前身である。

今回は、台6線道路の対岸出磺坑から歩きはじめ、台湾初めての油田やぐらを見て山にとりかかり、出雲古道を登った。現地では陸軍歩道或いは法雲寺步道と呼んでいる。出雲古道は、出磺坑と法雲寺を結んでいるので、この呼称である。鞍部に早く到着、そこで鞍部を挟んで南北にある、金童山と玉女山とを登り、法雲寺へ下った。山の山腹にある法雲禪寺からさらに大湖の谷間に下り、後龍溪の左岸を行く道路を大湖の街へと歩いた。

Hike from north to south

To appreciate the geology, history and culture of a place, walking is the best way to do it. At a speed of one's walking, you can find a lot of thing as you go. If you go on foot, you feel the terrain and environment through your body. You can stop and take a look or do things whenever anything attracts your attention. This is the baseline concept of Laknus Seilu trail (樟之細路). You walk along the trail and appreciate the places though which it passes.

All members at the summit of Yunv-shan

On our two-day trip of Laknus Seilu trail in late last month, we did not trace Chuyun historic trail (出雲古道) due to not enough time before dark. leaving this section uncovered. This trip was to complete that section and to have some more additional hike to adjacent mountains. We started from Chuhuangkeng (出磺坑) to get to the trail head on the foothill. Climbing to the highest point on the ridge line found the time was still early. We decided to go to Mt. Jintong-shan (金童山) and back before continuing the historic trail. The round trip to Jintong-shan took us not much time so after lunch we tried to another peak, Mt. Yunv-shan (玉女山), which is supposed to be a partner of the Jintong-Yunv pair (meaning a golden boy and a jade girl who serve Taoist deities). Upon completing a round trip to Yunv-shan, we made a visit to Fayun-si temple (法雲寺) and went down to the valley. The vally of Dahu (大湖) is famous for its strawberries. Almost all flat fields are strawberry gardens. As we walked along a country road going parallel to Houlongxi river (後龍溪) we came to one of such strawberry fields where farmers were picking fruits. We bought freshly-picked strawberries from them at a fair price. We finally walked to the town hall of Dahu to complete our hike.

#105 Ziqianghao express train

Despite an optimistic weather forecast, the scene from a window of Zijiang-hao (自強號) express train heading for Miaoli (苗栗) does not look optimistic at all. The sky is overcast and even streaks of rain hang on the window pane. I wonder whether we can leave the gloomy sky of Taipei behind today. Upon stepping out of Miaoli station a little after a quarter to nine, we find the road surface is dry though cloudy sky hangs over. Our bus of #5657 line bound for Shitan (獅潭) leaves the terminus of Xinzhukeyun (新竹客運) transportation company punctually at 9:00.  Our almost empty bus picks up mostly elderly passengers as it passes through the streets of Miaoli. They seem to have bought groceries in the town and to head back home.

Chuhuangkeng suspension bridge and elevated express way

Preserved #1 oil rig on the platform

Mountains come closer after the bus gets out of the town and passes over a bridge to cross wide Houlingxi river. The top half of the mountains is in thick mist. Approximately 40 minutes of  ride takes us to Chuhuangkeng bus stop (出磺坑站, elevation 185 meters) on the route 6 (台6線), which is just by a suspension bridge. Across the wide river runs the elevated rapid highway #72, which links Houlong and Wenshui (汶水). We set off at 9:47 and cross the suspension bridge to get to Chuhuangkeng. We take left after crossing and goes a little to find a preserved ancient oil well No.1. Yes, an oil well, Taiwan produced crude oil in the past!

Oil museum
 A monument and disused #3 rig on the hill

It is said that an oil oozing spot was found in 1861. At the time of discovery people thought it was of sulfur so the name Chuhuangkeng (meaning sulfur emitting depression) was given. Local merchants started to collect oil and sold to public. It was then controlled by the Ching government (清朝). It later came under a control of the Japanese regime. In 1903 Taiwan Oil Company (台灣石油會社) was formed to take over the oil business. CPC Corporation (中國石油公司) now controls it. Oil is no longer in production but natural gas is still abundant and its production is still running. The particular oil well numbered No.1 was built in 1877 under a supervision of American engineers with American components. This rig operated for a short period because oil ran out but this should be the first oil well in Asia and retains its historical value.

Trail head by Chenghuang-miao shrine
Trail "terrain" map
Next to the legacy oil well a museum of oil stands and some more remains of old wells and surrounding areas are open for public. We pass by them and follow a paved road up to the trail head, which opens just by Chenghuang-maio shrine (城隍廟). The sign shows the trail as "military trail (陸軍步道). The trail goes on a short red brick pavement and gets onto a steep paved road, which leads to a junction in a short while. There is a map by it and red big letters read "for Fayun-si temple" on a moss-covered left road. The very steep road looks slippery. We come up to a bottom of stepped dirt trail at 10:30 where a sign shows the direction.

A head of Fayunsi trail
The trail passes by a large metal water tank and keeps going up. It reaches a small shrine with a few benches at tis front yard. This is supposed to be a vantage point, but we only can see the valley bottom. Mountains from the middle up are all in while mist. After a short rest we continue our way up again on a paved road. The short paved road connects to another trail paved with stone blocks. A new map board stands just by its head, which indicates the trail is called Fayun-si old trail (法雲寺古道). This is a second different name of the same trail.

A nice clean trail

Climbing s steep section
The stone paved trail is really in good shape except a newly fallen tree trunk or two, which reaches its highest point on the ridge line with a wooden observation deck at 10:55. Mist gets thicker at this height of 430 meters above the sea level and we cannot see any distant view. It is still pretty early to go down to the valley. We decide to make a round trip to the summit of Mt. Jintong-shan. The trail to left leads to a head of the path to Jintong-shan. This trail is in fact a maintenance path of Taiwan Power company and soon a high voltage tower shows up. In a few minutes we come to the junction and take a right path to go up. It passes over a couple of dummy peaks and climbs a final steep uphill. We reach the summit (elev. 506m) at 11:17.

This peak is pretty pointing and all sides drop off steeply, Its north side reveals some view but thick mist hides view except the valley of Wenshui where some houses and streets are visible. We take the same route back to the junction of Chuyun trail, where we reach just before noon. Clouds break out and the sun shines through clouds, which makes the same place brighter and feels better. This gives us a time of leisurely lunch.

Back to the highest point of the old trail

Traversing the mountain side
After a half hour lunch break we take another direction of the maintenance path going over small humps. The sky is now clear and we can have a nice view over the valley and its surrounding hills. The community of Chuhuangkeng is just below our feet. The ridge path leads to a junction and we take left soon to meet a head of trail to Yunv-shan at 12:40. The path is narrower but obviously well traveled. It passes through bamboos and traverses a mountain side. It reaches the bottom of a steep climb in ten minutes. The trail surface is pretty slippery. Thankfully ropes are fixed at such points. We make it to the summit (elev. 580m) at 13:03. A tree encircled peak does not yield views around. A member takes our beer for us to share. It tastes good! The warm weather today and our climb to up here makes beer the best drink!

Summit of Yunv-shan
Return to the junction
Going over a debris
We carefully trace back the same path to the junction, which takes us a little more than twenty minutes. The wide trail is in fact paved with concrete and gets very slippery at some points. It is obviously seldom maintained and we come across fallen tree trunks and a large debris of land slide. At 14:00 we come to a junction of Chuyun old trail, where a large explanatory board of the trail and two benches are placed.

Disused toilet booths, steel gate at the end
The trail to the temple soon comes to a long array of disused toilets on one side, which looks to be composed of dozen or more of individual toilet booths. It makes us wonder why so many of such toilets here and left decaying. We pass through a gate to enter a large temple complex of Fayun-si. 

Stone monument of Dahu pionners
Cherry in full bloom
We take a right path at a small open space to a main hall of the temple. A stone monument of Dahu pioneers stands by the path. A large front yard of the main temple hall affords a good vantage point. Ranges of mountains and a valley of Dahu spread before our eyes. The peak of Mt. Yunv-shan that we placed our feet a while ago stands near on our right. Cherry trees by the hall are in full bloom. The sunny weather makes everything bright and cheerful.

Spacious front yard and the main temple hall
Temple main gate
A narrow footstep path leads from the side of the yard down to a stone main gate of the temple. From there a paved road goes all the way down to the mountain foot. At a junction we take a right road, which goes parallel to Route 3 road (台三線公路) across Honglongxi river. The route 3 road is very busy while this country road is almost free of traffic, good for strolling. All around are strawberry fields. A pyramid shaped mountain stands over the fields. It is Mt. Jintong-shan we climbed.

Tudigong shrine by the country road
Getting back to the warehouse to buy fruits
The road goes up a little on the hillside. It passes by old farm houses and a Tudigong shrine (土地公). A half hour walk bring us to a field where two women are picking up strawberries. Members negotiate with them for buying strawberries. One of the two who happens to be the owner tells us to go to a warehouse with her. We then go back a little to the house and everybody buys a pack or two of freshly picked strawberries.

Intersection of Route 3 road
Aboard #5656 bus 
We leisurely walk further down on the country road for fifteen minutes to a bridge to cross the Houlongxi river, which soon joins the route 3 road at 16:10. In contrast to the road we have just come along, the route 3 is really busy with a lot of cars and trucks passing. A short walk on the busy road bring to a junction towards the town of Dahu, which is built on a hill. We climb to a corner of the town and go to the town hall where our No. 5656 bus leaves for Miaoli at 16:33. We have a dinner at an eatery shop near the train station and leave for Taipei by 18:39 train.


------------------------------

Flowers by the country road

An easy hike combined with a nice weather made this trip very enjoyable. The distance was 14.8 kilometers, which looks rather long but a large part of it is easy paved roads. The total ascent was 829 meters and descent 679 meters. The total time inclusive of breaks was 6 hours and 40 minutes, which amounts to 25 of the route physical index. It is worth visiting Dahu in late winter and early spring when all fields are full of strawberries. Finding local histories like crude oil production is very interesting and educational while you enjoy fun of hiking.

2022年2月5日 向天池山 - 面天古道 - 楓樹湖 Mt. Xiangtianchi-shan - Miantian trail - Fengshuhu: Wet trails & flowers

楓樹湖の木蘭花 Magnolia flowers of Fengshuhu
台北陽明山連山の西端に位置する面天山や向天山は、MRTの車窓からでも見える、市街地に近い山である。その山は、向天池を抱える。ちょうど火山の火口に位置するような感じだ。この池は好天が続くと干上がり水はない。この池の名を冠した山が向天山から連なる尾根上にある。かなり以前に訪れたきりだ。樹木に囲まれ展望はない、ちょっとした丘という印象であった。

南側から出発、Start from the south
台北近くの山は、訪れる登山者が多い。そうしたなか、新しく道も開かれている。向天池山の北西の山すそより、直接当山に登る道が開かれた。この道は、その登山口のすぐ近くにある天元宮から向天池山と向天山との鞍部へと登る山仔頂古道とほぼ平行に、尾根を登ってくる。過半は、地元住民が設置している水管の保守用の道を利用している。尾根上をストレートに直登するので、部分的にはかなり勾配がきつい。

楓樹湖、背後は二子山 At Fengshuhu with Mt. Erzi-shan behind
今年の台北の旧暦正月は、雨が連日のように降った。その雨が止まり、少し回復した隙間に今回の山行を行った。向天池山登頂後、向天山と面天山を越え、面天古道と廃棄された水管路を経由して淡水の楓樹湖へ下った。楓樹湖は、二子山と向天池山から北へ伸びる尾根の間の谷間に開けた、比較的勾配の少ない場所だ。湖という文字があるが、日本語での「みずうみ」ではなく、台湾語で平らな場所を示している。台湾のほかの場所にも多く、湖の名前を持つ地名があるが、水のある湖ではない。もちろん、本当の湖もあるが。天気が良ければ、北側に海岸線が望める。春には木蘭花が多くの場所で咲き、たくさんの遊楽客を引き付ける。

--------------------------------------

Located at the west most point of Yangmingshan mountain range (陽明山山列) Mt. Xiangtianchi-shan (向天池山) stands as one of the three adjacent peaks including slightly higher Mt. Miantian-shan (面天山) and Mt. Xiantian-shan (向天山). It is very close to the streets of Taipei and can be easily identified from the town of Beitou (北投) and its vicinity. I visited this peak a long time ago via Shanzaiding trail (山仔頂古道). I recently discovered on a map a new trail running parallel to it and directly reaching the summit of Mt. Xiangtianchi-shan. A little study revealed that hikers themselves had lately made it through. It aroused my curiosity as I was considering to make a visit to nearby Fengshuhu (楓樹湖).

The location of our hike relative to surrounding towns and mountains

Fengshuhu is a gradually inclined slope spreading in a valley between Mt. Xiangtianchi-shan and Mt. Erzi-shan (二子山) and known for its flower gardens, particularly for magnolia flowers (木蘭花). These flowers come in full bloom in February through March. There are also many cherry trees, mostly of Formosa cherry (台灣山櫻), planted all around the place, which also bloom in February. They attract a crowd of visitors in this season. A few friends and I visited Fengshuhu several years ago to appreciate the flowers in spring. So my plan of this hike came into being: Climbing Mt. Xiangtianchi-shan via the new trail and going down to Fengshufu to enjoy flowers.

Northern Taiwan was very wet during the lunar new year days. It rained almost every day throughout the nine days of holiday (Jan. 30 through Feb. 6) except last two days, on one of which we made this hike. Long rain saturated the surface soil of the trail and made it very slippery. The new trail goes very straight on the steep slope and made it worse. The trails we took for descent were not so steep and yet your foot slips if not careful. After a hard time we finally made it to Fengshuhu welcomed by beautiful flowers, which was well worth coming through the nasty trails. So this hike was of wet trails and flowers!

------------------------------

The trail head of the new route is located at the northwest foothill of Mt. Xiangtianchi-shan. A little lane named Nanshipu No. 32 (南勢埔32巷) leads to it. There happens to be a bus stop of that name serviced by F103 line. F stands for "Free" of charge. This bus service is one of many similar transportation services sponsored by New Taipei City government (新北市) for rural communities. This particular line goes on the same route of commercial buses like No. 875 line through the densely populated area of Danshui (淡水) and branches off to serve small communities on the hillsides, which commercial buses do not reach. Nanshipu is just one of such communities. This bus service is in fact a big help for hikers like us though it is primarily intended to serve the local population,

Danshui bus terminus is next to the MRT station
Alight from F103 bus
F103 buses depart from Danshui bus terminus next to the MRT station. Our bus leaves at 7:50 and we met at the gate of it before that. We have seven people today. The bus leaves on time almost full of passengers. It goes through main streets of Danshui and passes under the light railway system. It then climbs along Beixin road (北新路) to the foothill. Just before Tianyuangong temple (天元宮) the bus turns right to go up a hill. We reach our bus stop (elevation 253 meters) at 8:17. It is rather desolate under a overcast gray sky. The road is wet but thankfully no rain.

First junction to take right, note white notices
The mountain is in cloud
After a few minutes of preparation we set off. Passing a couple of houses the road turns a dirt road and we take right at a junction. Three notices of land auction sale conducted by the government are placed by the road. The road soon ends at a tea plantation with a worksite hut. The mountain above the plantation is in cloud. Our trail starts by the hut. As we go up a view towards north opens up, showing a hazy coast line. In near front we can identify the tower of Tianyuangong temple. The trail leaves the planation and gets into woods.

Tower of Tianyuangong is visible between trees, coast line far behind
Two poles of wishes
At a junction (elev. 367m) where two stone poles stand side by side with their surfaces engraved such words like world peace, prosperity to the nation. The location and such words make me wonder how these poles were erected. We take the right trail and continue climbing. Two water pipes go along the trail. Passing an abandoned small tea plantation we get into an untouched forest. There is a little undergrowth on the forest floor, which is good for not wetting our pants as we pass. The grade gets steeper and the trail gets slippery. A past few days of rain saturated the surface soil and made it very slippery.

Water pipes go along the trail
Steep climb continues
Passing a slippery stretch
Junction of big rock
At 9:10 we come to a junction where a traversing trail alongside of the hill crosses. There are few points of nasty climb on slippery grades with nothing nearby to hold onto. In another half hour a big chunk of rock (elev. 620m) suddenly shows up in front where a traversing trail branches off to the left. Water pipes go on to that direction, so there must be a stream of water for the pipes to catch water. The trail so far up here is in fact a maintenance path of the water pipes.

Steep climb continues
A low stone wall alongside the trail
A short flat stretch
A few more minutes of climb finds a low man-made stone wall going along the trail. This must have been of some use in the past but I cannot figure out for what. At 9:45 the steep trail finally gives in for a flat place but does not last long. The grade gets moderate as we proceed in denser undergrowth. At 10:12 the summit (elev. 881m) shows up. An open circle without weeds finds a marker stone in its center. This marker is new as there was no such stone on my last visit. We suddenly feel cold wind blowing through woods.

The summit of Mt. Xiangtianchi-shan
Rescue call marker #10
We leave for Mt. Miantian-shan after a short stay on the summit. A short decent leads to a junction with Shanzaiding trail. A marker plate of rescue call is attached a tree next to the junction, which did not exist on my last visit. This indicates that more and more hikers visit in the past few years so that the local authority had to cope with any incident on the mountain. We keep on the ridge trail, climbing back a steep slope in woods and out onto a grass field among thick mist. We swim through the sea of tall grasses and hop on to the stone paved official trail at 10:40. A marker pole of Mt. Xiangtian-shan (elev. 949m) stands just nearby.

Ducking through tall grasses
At Xiangtian-shan
Solid stone steps are welcome today
The solid stone steps feel good after the long struggle with the slippery trail, though we usually despise stepped trails. Thick mist envelops Mt. Miantian-shan which in fact stands just in front. The trail goes down and up again to reach the summit (elev. 977m) at 10:54. A thermometer attached to a direction sign pole shows mere six degree. The temperature at a Taipei flat place is about 15 or so during the recent cold spell, so  this figure makes sense. A crowd of hikers are at the observation deck on the other side of the summit. They look like a group of school students.

A group is by the observation deck
This little opening in bamboos discourages to get in
Our original plan is to follow a ridge route down. As soon as we see its small opening in dense arrow bamboos (箭竹), I decide to give up this time. We would get soaked wet if we proceed in such vegetation. Besides the temperature is so low that it is not wise to get wet. We keep on the official trail down, passing the crowd of students who go down slowly. The trail reaches the bottom at 11:18 to join a trail coming down from Miantianping (面天坪).

Going down along the stone paved trail
Remains of Miantianping stone houses
Passing a stream bed of the old trail
We take left and go down a wide trail which soon splits into two. These two trails join again just before Erziping (二子坪). We take the left stone paved trail going along a creek on our right. In a few minutes we come to a remain of Miantianping stone houses (面天坪石屋遺址, elev. 735m).  An explanation nearby shows that the stone houses used to be a home as well as buffalo barn in the 19th and early last century. We take Miantian old trail which starts just by the stone wall. The trail soon gets down onto a creek floor and follows through moss covered rocks, small and big. It then gets up onto the right bank and further up on to a plateau where a trail coming down from Mt. Erzi-shan meets.

Iris flowers by the trail
Trail passes through nursery
The gradually descending trail passes by wide fields of iris (鳶尾), some of which are in bloom. A farmer happens to be attending the field and we exchange some words. The trail then pass through tea trees, nursery of needle leaf trees and camellia flowers to Bailaka highway (百拉卡公路 elev. 672m). A friendly dog appears from nowhere and welcomes us. An eatery shop is just by the road. One of the members suggests to have a lunch at the shop. The time is a little past noon and we get into the shop. It offers fried rice and chicken soup which would worms up our chilled body. Apparently the shop did not expect to have guests on a day of such wet weather and it takes a lot of time to fill our order. Eventually after one hour of rest and eating, we get out of the shop only to find how cold it is outside.

Coming out onto Bailaka road
Lunch at an eatery shop
Take a dirt trail again
We follow the paved Bailaka road for a while and get onto a dirt trail again at 13:14. It mildly goes down for a while and gets steep to meet a trail in a few minutes. On my last visit we took the right while we take the left instead to reach Fengshufu. The left trail soon gets down to an abandoned water supply duct. It looks that this has been disused for a long time. There are tons of obstructions along the way including tree branches and fallen trunks. Some sections of the traversing path are very narrow with a steep cliff on our right side. In addition to that, it is wet all the way. Thankfully ropes are fixed at very precarious stretches.

Going along the abandoned water duct
Steep descent
Finally reaching Fengshuhu
After twenty minutes of nervous traversing we come to a point of going down. This descent is by no means easier. Stone steps are placed at some points. They are all wet and steep. At 13:52 we come down to a stream of Gongsitianxi (公司田溪) at last and cross its moss-covered stream bed. A water duct follows from the stream and we walk along it to a stone walled house with an old and tall lagerstroemia subcostata tree (九芎樹). A paved path leads down to an observation deck. We are now at Fengshufu. A crowd of visitors are all around. Even a temporary food stand is set up by the deck. We go down a little further and have a break (elev. 373m) at 14:10.

About a half of magnolia flowers are in full bloom
Magnoloia trees are planted even in a vegetable garden
Cherry trees are everywhere in the village
Gardens of magnolia flowers are all around, half of them yet to bloom. Cherry blossoms and camellia flowers add beauty to Fegnshufu's spring. Finding so many visitors around, I decide not to go for our original route but to go directly down to Beixin road to catch a bus, by which we can avoid a huge crowd of people around Tianyuangong temple. To my happy surprise we find more flower gardens as we go down along the stepped trail and a paved road. Fengshufu is indeed a village of magnolia flowers!

Going down under cherry blossoms
#875 bus has just come
As we come down along, a bus stop of F103 stands by an intersection. It is named Fengshufu bus stop. A bus will not come for another half hour so we keep on the paved road further down. Cherry trees are in full bloom along the road. We reach Beixin road at 15:05 and soon see a bus stop of Guanguang Guoyuan (觀光果園, meaning tourism orchard, elev. 197m) a little further left on the road. In about ten minutes our #875 bus has come. On our way we see a lot of cars are parked near Tianyuangong temple. We encounter an almost  choked road with an endless line of incoming cars to the temple. Our bus takes about 35 minutes to bring us back to Danshui MRT station.

It was cold and damp on the mountain. The weather did not turned out as good as I hoped. Nonetheless it did not rain, for which I should be thankful if I consider rain lasted so many days prior to our hike. When we came down to Fengshufu, we were out of miserable mist and had a good time to enjoy flowers. Spring brings a lot of flowers of many kinds to mountains. We can enjoy them from now on.

Our hike took six hours and a half inclusive of one-hour break for lunch. The distance was approximately 9.5 kilometers with a total ascent of 840 meters and descent 804 meters. The route physical index amounts to 22. The traversing trail along the abandoned water duct is not in good shape so I would not recommend for beginners to enter. The other sections of our route are OK, though the new route to Mt. Xiangtianchi-shan is demanding and slippery after rain.
