River tracing boots
Easy and nice. It has several clean nice pools. Many butterflies and shrimp. There's a 4 meter waterfall at 24.96,121.9085 that you need to climb over. At the end of the trace is a 8-meter waterfall. If you go above the 8-meter waterfall, two really tall waterfalls are around the corner. The one on the main stream is around 20-25 meters tall, and the other one on the left fork is also around that height. We went around the waterfall on the right side(facing downstream) and did a little bushwhack, but it was quite easy in general. There's webbing and a rope on the other side but it looked very sketchy to climb up, so we didn't go up on the left side(facing downstream).
