Roughly 3-4 hours there and back. We took a trail out which made the return trip faster.
- You'll find one decent dry climb. There may or may not be a rope. When we went someone had moved it to the top so someone would need to go first and toss it down. - Lots of frogs so it's also possible you see snakes. Ran into one myself though I believe it was non-venomous.
Info not yet provided, feel free to add it,
- You can take a bus to the trail to enter the trace or find parking at this location: 25.246974, 121.558699. Walk down the trail to the very end and you'll be able to get into the water just past where the river forks. You will in fact be on the wrong side of the fork, so you will need to backtrack downstream for around 2 minutes and get into the other branch located at the starting GPS point. With the exception of one climb near the end, this is a fairly easy trace. If the rope is present even that isn't much. Clean water, with tons of frogs.
