4-6 hours one way from the parking lot.
Falling rocks. Accessible only in dry seasons.
At least helmet, life jacket and river tracing boots.
Not a beginning route. Swift water crossing is foreseeable. Beigang River Hot Spring No.1 is a concrete hot spring pool. Every 5 years there is a construction in progress deep in the river, thus a construction road where you can walk to the hot spring easily for 2-3 hours. The other years you need to trace your way there because the construction road no longer exists due to typhoon.
