Leading river traces regularly on my Meetup or Instagram 12 seasons a year.
Beginner-friendly. A creek where hot spring sources are everywhere. Beautiful colorful walls that are usually seen only in the gorges deep in mountains. A hot spring cave that can contain 6-8 people(38-39 degree Celcius).
Warrior's Waterfall, named after an Atayal rebel called Mona Rudo against Imperial Japan, losing his last battle near the trail head of the river trace.
Amawan Waterfalls. Very beautiful! A natural bouldering gym. Emerald green deep pools. Quite a few waterfalls. The fifth waterfall is about 30M tall if I don't remember it wrong.
