Suspension bridge & waterfall
2 km, 1 hr. Great and picturesque view. Further down the road in addition a great view from the bridge.
An easy 2-km, 45-min walk from the park office at Lushui to Heliu. Winds around short cliffs above the main road. Does pass through one dark tunnel, so bring a flashlight.
錐麓古道
A strenuous hike that used to be part of an old cross-mountain trail through Taroko Gorge, starting near Swallows Grotto as it winds upwards through the green forest and coming out on a narrow cliffside path 700 m above the road but not more than a meter or two across. Not for anyone with fear of heights, but offers stunning views of the mountains on the other side of the gorge. Fortunately there's a cable to hold onto, but still, be careful and don't bring small children. At the 3.1-km marker after the narrow cliff trail is a flat area that makes a good place for lunch or a snack. The trail ends there as further tracks have high risks of rockfall and landslides. There are lots of monkeys in the area around the trail, so look and listen for them snacking on leaves up in the trees. Hikers are limited to about 150 a day, so the trail is peaceful compared to the relative crowds below. Apply as early as you can as permits do run out, sometimes within minutes of becoming available at 07:00 one month in advance. The permit lets you start the hike between 07:00 and 10:00—try to make it early (before 08:00) to have the trail almost to yourself. Apply at https://npm.cpami.gov.tw/en/index.aspx; once you get the permit, print it out and bring it and your passport with you to check in at the trailhead.
水簾洞
An easy 2.1-km trail, 2-hr round trip. Named for the cave at the end of the trail, where water literally pours down in sheets from the roof. Pack a poncho or use one discarded by other considerate hikers (or inconsiderate, depending on your point of view). Hiking to this point on the Baiyang Waterfall Trail takes you through many very long, completely unlit tunnels — an experience in and of itself. Be sure to take a torch/flashlight, or you'll be walking in pitch black darkness. The first part of the trail is wheelchair-accessible.
