2-5 hours one way.
High water flow.
River tracing boots, life jackets, helmets, floating rope at least 30 meters, and the gear for an anchor.
Kakalang Hot Spring locates in Walami. The name Kakalang means "the place with a lot of crabs" in Bu'nun. (23.341685,121.222860) The water flow in Lele River is as strong as it is in Jianianduan, so this river trace is definitely an expert's route rather than a beginner's one. The outcrop is 58 degrees Celsius, but a pool for at most two people is only possible with a very big tarp and great effort for half a day, probably not the best wild hot spring in the world, or far from it. There is another pool in the sand with slightly warm hot spring water, one hundred meters from Kakalang's main outcrop--so little warm that it is even kind of chilling on a winter day.
