[quote=“ac”]There seems to be 2 main trails - one if you cross the bridge in the centre of Wulai and take an dimmediate left; the other if you cross the bridge before Wulai, go through the entrance gate, and follow that road to the end (passing the cable car). Which is the Tonghou Trail ?
The first one you mentioned is the Tonghou trail. The second one you mention I don’t know what it’s called – we call it Monkey Trail on account of we often see monkeys up there. It takes you over and out at the Fushan forest preserve or biological station or whatever its called. You’ll be a very long way from the station. Definitely a hitchhike and there’s not much traffic because again, the forest preserve area is tightly controlled and you can’t get in without a reservation. I haven’t hiked right through but I’ve been in from both ends (oo-er, missus!). Most people I’ve met on the trail have been doing it as an overnighter.
The Tonghou trail on a bike would be sweet indeed – a lovely easy tarmac road for about 15-or-so km (?) with, as I said, limited traffic, followed by some funky singletrack, followed by a murderous carry-the-bike ascent to the watershed (but not really too long), followed by a glorious coast all the way down to the Yilan plain. It’s really really cool to set out from deep-in-the-mountains Wulai and come out on top to stunning vistas of the Yilan plain and the Pacific.
