Lele River has high water flow all year round. Even one crossing could be difficult.
Helmets, life jackets, river tracing boots, a floating rope > 30 meters, harnesses, and equipment for an anchor.
The ending GPS spot is Nan'an hot spring, incredibly close to Walami trailhead. However, Lele River's currents are usually so strong that only professional teams are suggested to visit there. The hot spring water is 47 degrees Celcius and a proper pool for 4-6 people can be built. The path from paved road to the river is along the ridge and find the right way down.
