About 4km past Wulai Waterfall is this forested area popularly known as Wawagu (Valley of the Frogs). With its hiking trails through broadleaf and cedar forests, bird and insect life, river views, and rushing waterfalls (especially the three-tiered Hsinhsian Waterfall; Xìnxián Pùbù), this place is worth a dedicated trip. It's particularly enchanting on a misty winter's day.
If you don't have a vehicle you can walk to Neidong from Wulai in about an hour. Take the pedestrian walkway along the river or the minitrain to the end of the line and then make your way to the main road. After you pass through a small tunnel, cross a bridge to the left and follow the road on the other side upstream to Neidong.
