- 1. Numerous landslides have previously occurred on the 820 Forestry Road. Please be careful when crossing these areas.
2. The trail markedly ascends in elevation past the Mt. Bilu trail entrance at the end of the 820 Forestry Road. Ropes have been installed at the steeper sections to assist hikers.
3. Hikers will need to carry at least 2 liters of water for cooking (dinner and breakfast) and hiking (~12 hours total). The water source on the ridgeline is difficult to reach.
4. The original route to Mt. Yangtou (along the river valley) is precipitous due to steep cliffs on its east side, causing landslides and rockfall during periods of heavy rain and numerous casualties. Considering these reasons, the trail has been rerouted in 2004 to the current route from Ci’en to the ridgeline junction.
5. Please take care to not lose your way through the bamboo forest.

The Bilu-Yangtou traverse usually begins at the entrance to the 820 Forestry Road, adjacent to the north exit of the Mt. Hehuan Tunnel at Dayuling. This route will travel eastwards from Mt. Bilu to Mt. Yangtou, and descends roughly 700 m over the course of the traverse. Hikers can also choose to start at the 132.4 km marker of Provincial Highway 8 and travel westwards towards Dayuling; however, due to more stringent constraints on water sources, distances to available campgrounds, and overall hiking time, most hikers will prefer an eastward route. At the Bilu river on the 820 Forestry Road, which is the last and only available water source en route, hikers should refill at least 2 liters of water for cooking and hiking to last the remaining portion of the traverse.
The combination of a heavy pack (food plus tents), 2+ liters of water, and steep terrain for the majority of the traverse will test a true hiker's endurance. Many hikers choose this route to relish the great wilderness. Upon reaching the ridgeline, hikers have the opportunity to put down their rucksacks and observe the panoramic view at the Mt. Bilu triangulation point adjacent to the trail. A campground is located five minutes past the junction.
Geology and Ecology
Mt. Bilu: 3371 m (elevation); #39 in the Taiwan baiyue (a list of Taiwan's 100 most spectacular mountains)
Mt. Yangtou: 3035 m (elevation); #98 in the Taiwan baiyue. Mt. Yangtou gets its namesake ("sheep's head") from the shape of the mountain, which resembles a sheep's head.
Mt. Ju: a series of 7 peaks stretching across 2 kilometers, with the highest peak at 3276 m elevation. As its name suggests, the series of peaks resembles a sawtooth. Mt. Ju is one of the "9 cliffs" of Taiwan's mountains. Its forests are primarily comprised of Taiwan fir (Abies kawakamii), with Yushan bamboo (Yushania niitakayamensis) interspersed among the trees.
