2021年4月18日 宜蘭南山村 佐米縱走 佐得寒山 - 米羅山 ヒノキ神木ルート Trek of Yilan Zuodehan-shan - Miluo-shan ; a route of giant cypress trees

南山神木 Nanshan divine cypress tree

台湾のヒノキは有名だ。日本では阿里山のヒノキが知られているようだが、実は阿里山に残るヒノキ神木はもう少ない。阿里山以外にもまだヒノキ巨木が残る。今回の宜蘭縣の奥、大同鄉南山村の背後には、まだ多くの樹齢数百年千年単位のヒノキが残っている。歩いたルート脇で数本の巨木を見た。今回は英語で記述します。


Taiwan was once known for its abundant giant cypress trees. Many had been cut down and they have since become very rare. It is fortunate that we still can appreciate them in remote mountains. There are several places in Taiwan where the population of cypress giants is rather high, such as this hiking route called Zuo-Mi trek route (佐米縱走). You can meet several giants as you go along the trail. The cypress giants survived for hundreds even thousands years. If you stand by one of these giants, you realize how tiny you are. You are struck with awe feeling regardless of your religious background. They hold such power to make you humble. Compared with their size and life span many times over our human being, no matter how great you are in the human society, you are just insignificant and powerless in the wildness.

Start from the south by the route No.7A

Trail head by the route No.7A

This hiking is in fact one of our two-day activities. We visited Mt. Xiangben-shan (香本山) located just north of Nanshan-cun village (南山村) yesterday. We stayed at a minsu inn (民宿) overnight. We have two cars and one of them has been just parked near the trail end of our hike early in this morning so that we can fetch the other car easily after our hike and expedite our movement of going home. 
It is 6:40 a.m. now and nine of us are at the trail head by the route 7A (台7甲線, Elevation 1310 meters), which is at south of the village. Many untidy water pipes from nearby streams are running along the route 7A supplying water to the village and cabbage fields all around it. Cabbages are a main local crop.

Start with a steep but nice trail

keep ascending

The trail goes on a steep slope leaving a small stream behind. It goes under a wide-leaf tree forest. Unlike the path of Mt. Xiangben-shan yesterday, it is pretty clear to follow. You just keep ascending and gaining the altitude. At 7:20 we have a short rest at 1520m in attitude. We have gained the height of approximately 200m in forty minutes, which is good. This is due to the nice condition of the trail. I shuffle the position of members in the troop by placing the slowest member just behind me. The speed of the troop is defined by this person, by which the troop can stay together.

A wide and gentle ridge

A very clear path going on the ridge
As hiking has become more popular partly because no overseas travel is available nowadays due to the pandemic, we hear more reports of missing hikers. Some of them were eventually found dead. It is reported that these hikers often walked alone far behind the fellow hikers. They walked far behind because they walked slower than other hikers. If they had stayed together in a troop, fellow hikers would have surely taken care and no such tragedy of missing person had happened. If you like to walk on your own speed, you can do it alone, not necessary to join a troop. This is my policy of taking people in my hiking activities. Our members are fully aware of this point and very cooperative and helping each other, which I appreciate very much.

Sun shines through woods
Generally good trail but fallen logs too

At 7:32 we get on a well-defined ridge line down from the summit. As we go higher on the ridge path, sun shines through trees and make the forest bed bright. We had rain all day yesterday and this sunshine is very welcome. At 7:53 the route No. 7A is visible very far down at our left through trees . We are now at around 1730m in elevation, which is more than 400 meters higher from the trail head.  We have already covered more than half the climb in terms of altitude.

Usnea is hanging from tree branches

Going by dense cane bushes
A little after 8:00 we come to a flat place where usnea (松羅) is hanging from branches of trees all around. This gives us a feeling that we are deep in mountains. Green moss on tree trunks adds more of that feeling. A thermometer is attached on a tree trunk showing 8 degree in centigrade, which is obviously wrong. It must be more than 20 now. At 8:20 we make a short break at 1840m in elevation. We keep going up on the last part of climb to the summit. At 9:00 we get very close to the summit where a thick growth of thin cane (箭竹) appears. We keep on going between cane bushes for another several minutes. We get to the summit (elev. 2082m) with a triangular marker at 9:09. This is the highest point of the hike today and we have a good rest before continuing.

The junction
We set off at 9:43. The trail goes rather flat for a while to a junction. The trail left leads to the main ridge between Mt. Tao-shan (桃山) and Mt. Kelaye-shan (克拉業山)  via Mt. Tayafu-shan (塔雅府山). The sign at the junction says it is a long way and the path is not clear. Compared with the trail we have so far traveled, the left path is indeed beaten and covered with thick fallen leaves and grasses. We take a the right trail and go down. The forest bed is full of fern. At 10:12 we find the first cypress giant in front. The back of the giant trunk is hollow, but it is still alive and strong. Our members go near it, which unintentionally reveals how huge the tree is.

We keep on a gradually descending trail and come to a camp site with water supply at 10:40. It is rather wet but a constant water supply led by a pipe from a nearby stream is very good. We continue our way and get to the second cypress giant at 10:48. This one is as big as the first one and named "Nanshan Shenmu" (南山神木, Nanshan divine tree). A large flat field is in front of the tree and we have a rest for lunch.

The third giant cypress
Three-legged giant tree
As soon as we leave the Nanshan Shenmu tree at 11:33, we come across a junction. The right trail goes up onto a ridge line while our trail left is going down along the slope on the north side of the ridge. The right trail is obviously less travelled. Going over a rather big fallen trunk, we come to the third cypress giant. This one is also with a hollow back, but is yet very lively. On our way further down, we come across a big tree with three legs and big hollow room under it, which can accommodate several persons.

The trail then starts a gentle ascent and leads to another cypress giant. This one was cut off at its middle. This was done by a group of illegal loggers in 2012. A board next to the tree explains that 20 members of the group were later arrested. Cypress trees have a high economic value. Even though efforts have been made to eradicate illegal logging, not yet complete. Recent increase of hikers may add more chances to expose illegal actions of this kind and may hopefully have some deterrent effects. Fortunately this particular tree is not dead. The biggest trunk was cut off half, but the three remaining thin trunks are thriving.

Notice by the tree

Moss-covered big stump
Straight cypress giant
As we go on the trail we see a smaller giant cypress and a big stump covered with green moss. This giant was sadly cut off completely at its foot. We keep on ascending and meet a very straight cypress giant in front. Our trail gets leveler and passes mussy sections. The trail coming over the ridge line meets ours from right and we soon come to an open flat place at 12:30. A hut stands just nearby. Its opening is sealed with planks and tree branches. The plate by the opening says Nanshan village cypress trail field tradition and culture station (南山部落檜木步道山林傳統文化說明站). This hut must be used by the local people.

Mist is getting thick
Playing with the swing

After a short rest at the open space, we set off for our next and last peak, Mt. Miluo-shan (米羅山). The weather has turned from sunny this morning to very thick misty now, making visibility only a few meters. The trail goes up a little and passes by an unmarked junction. It goes right side of a small peak and meets another unmarked junction. The ridge gets very narrow. Another and final cypress large tree shows up on our right. 


At 13:30 we come to a place where a tall swing is hanging high up from a branch of a nearby tree. It is suspended with a thick rope and steel cable, which looks solid enough for play. All members but one take turns to play with it for a while, which is fun. A short dip and ascent leads us to a flat and wide summit of Mt. Miluo-shan (elev. 1750m) at 13:51.

Going down the last section

We leave the summit a little after 14:00 and go down a steep descent. We come to the trail end (elev. 1580m) in 10 minutes, which is just by a cabbage field. If the weather is fine, a nice and wide view should spread in front of us. Today it is very misty and you can only see our member walking just a few meters apart. Several local farmers are tending the field besides the road which we go down. They  are sprinkling fertilizer. 
At 14:25 we come to the spot where our car is parked. Two of our members take the car and go down to fetch the other car. The rest of us keep going down for another couple of kilometers and wait at a place on the way down. The two cars are coming up and meet us around 15:15. Misty light rain which started a short while ago turns to heavy rain as soon as we get on cars and start our way home.

We have a dinner on our way at Yulan (玉蘭) by the route No. 7 (台7線) and back onto our way home. The Hseshshan tunnel (雪山隧道)  known for its notorious congestion on weekends proves very passable this time. Surprisingly we have no stopping at all and arrive at Taipei a little after 20:00. 

The hike today gave us no view to enjoy and even rain at the end. But meeting many cypress giants is really nice and memorable. We walked 9.2km with a total ascent of 1070 meters and decent 1100 m, taking 8 hours and half including a rather ample rest time. The route physical index is calculated to be 29.


2021年4月17日 宜蘭大同鄉香本山 雨の不人気ルートを歩く

台灣檫樹のある香本山山頂

台湾の主要山脈のうち、雪山山脈と中央山脈は多くの高山を有し台湾島の背骨を構成している。宜蘭の蘭陽溪と今は亞口と呼ばれるピアナン峠分水嶺の向こう側大甲溪とがこの二つの山脈の間を分けるように流れる。雪山山脈は、その北端は三貂角で海から立ち上がり、南へ盟主雪山主峰へと続き、南へまた下がっていく。その長い山脈には名も知られない峰が多くある。今回の登山対象は、日本人の苗字香本と冠した香本山(標高1755m)だ。名前の由来がわからないが、主脈上の瑪瑙山近くから東へと延びる支稜上の小ピークである。訪れる登山者も少ない不人気山だ。

山頂を往復
南山村付近の二日の登山ルート
今回の登山対象選定には二つの理由がある。一つは、翌日に行う佐米縱走の前日でその近くで短時間で登れること、二つはいずれ克拉業山から北へと続く主稜線を歩くことがあるかもしれず、その下見的な意義があることだ。山道は、不人気山である所々はっきりしない部分もある。マーカーリボンはそこそこあるが、途中補ったところもある。天気が良くなく、ほとんど雨の中の登山となったので、余計に苦労があった。

宜蘭員林を通過、天気は思わしくない
6時50分に二台の車で台北を出発、今回は全員で9名だ。第5号高速を降り、7時55分途中のコンビニで休憩をとる。雨粒がウィンドシールドに落ち始める。天気はどうも思わしくない。台7線から台7甲線に入り、蘭陽溪沿いに登っていく。広い河川敷にはキャベツが多く栽培されている。川幅が狭まり、両側の山が高くなってくる。9時半前、南山村の前で右に進む道路に入る。両側のキャベツ畑の間を登り、9時45分香本山登山口(標高1090m)に着く。周囲は霧で真っ白だ。

駐車場所から望む、左は工事現場、全面の谷から登る
帆布シートの簡易池の脇を行く
登山口周囲は、土木工事が進行中だ。どうやら沢の砂防ダム工事のようだ。現場脇のスペースに車を駐車し、雨具をつける。気は重いが、仕方がない。10時に出発する。霧が濃く遠くまで見えない。山道は、どうやら工事中の現場を横切り向こう側の畑を回り込んでいくようだ。畑脇の道の突き当りから右に進む。沢を渡る。たいがいは見かける登山口を示すマーカーリボンがない。沢を過ぎると左に沢沿いに道が進む。そのうちにマーカーリボンを見る。周囲の様子もネット上資料と同じ青と白のストライプシートを使った簡易池が現れ、道筋が正しいことを確認する。

急坂にとりつく
急坂を登る
簡易池のすぐ右側から山道は急坂になる。勾配がとてもきつい。GPSの記録では60度あるようだ。頼りないロープがあるのが幸いだ。土は雨で崩れやすく、左右にはつかむことができる樹木がほとんどない。草も頼りないものばかりだ。中にはとげのある草もある。触ると痺れる毒草咬人貓まである。約40分ほど急坂に苦しみ、やっと尾根上に上がったようで勾配が少し緩くなる。広葉樹の間の道は、踏み跡が少しはっきりする。11時38分、道脇に山の字がある基石がある。標高は1500mぐらい。小休憩をとる。先ほどの急坂登坂開始前に折り返した一人に加え、二人が諦めて先に下山する。

尾根にとりつき坂が緩くなる
山の字基石
香本山東南峰
10分ほど進んで高度差を50mほど稼ぐと、右にちょっと頂上らしいところがある。基石もある。ここが香本山東南峰だ。古い山名表示が脇の樹木に取り付けてある。道は少し平らに進み、心持下る。その先から山頂へ向けまた上りが始まる。尾根はかなり細いナイフリッジも現れる。幸いロープが取り付けてある。12時46分、眼前が開けて大きな石が重なる広い尾根になる。石はみな苔で緑だ。標高も1650mぐらいで残り100mほどになった。倒木が道を遮る。道筋を見失う。方向を見定めて探すと、また踏み跡がある。最後の急坂を登り、13時香本山山頂(標高1755m)に着く。雨はまだ霧雨状で降っているが、助かる。

大石のセクション
山頂かの最後の急坂
雨の不人気中級山山頂、自分でも何が面白くて登るのかと思う。ただでさえ、樹木が茂る山頂は展望があまりないが、ましてや霧では何も見えない。ただ、この山には開発や森林伐採で少なくなった台灣檫樹が生えている。台湾の国蝶寬尾鳳蝶はこの樹木の葉しか餌にしない。そのため、国蝶は絶滅危機種になっている。霧雨のなかで食事をとる。

香本山山頂
倒木帯を下る
13時、白いシャクナゲが咲く山頂を去り下り始める。登りで通過した大石セクションは、道筋がわかりにくいので注意が必要だ。倒木部分は、逆方向からだとあまり迷わずに通過できる。14時21分、上りでは気づかなかった2006年8月日付の古ぼけた道しるべを見る。尾根を離れ、右に斜面を下り始める場所は注意が必要だ。雨でぬれている落ち葉の道は踏み跡がはっきりしない。

2006年日付の古い道しるべ
急坂を下り始める
登りで苦労した急坂は、下りも大変だ。わずかにある樹木も枯れていて頼りにならない。最後のセクションでメンバー一人が足を滑らし、少し滑落した。幸い途中で引っ掛かり、ほかのメンバーの手助けで事無く済んだ。15時15分、簡易池の脇に降りる。15時35分、登山口に戻る。泥だらけになった長靴や雨具を、近くにある水桶の水で洗う。歩行距離は4㎞足らず、登坂下降はともに650m、昼食以外はほとんど休んでいないが休憩込みで約5時間半だ。コース定数は18だが、雨と坂で苦しめられたので、感覚的にはそれ以上だ。




民宿で扇風機でぬれた衣服を乾かす


15時50分、南山村の民宿に向けて車で下っていく。5分ほどで台7甲線にでて、右に進む。10分足らずで、予約の民宿に投宿する。民宿は登山者が多く泊まるので、オーナーも登山者の様子がわかっている。雨でぬれたものを扇風機の風にさらし乾かす。シャワーを浴び、17時半隣の牛肉麵店で夕食をとる。民宿に戻り、雑談後21時には就明日の好天を期待して寝する。
