Chunyang Hot Spring (中文版：春陽溫泉) is a wild hot spring in Nantou, Renai Township. The hot spring flows out from many outcrops in the shale riverbed. The water in the pool is mild and warm, but the mud at the bottom is nice and hot. You can dig your feet in it or scoop it up and give yourself a hot mud bath. There are also several small holes in the rock wall with hot water flowing out of them.
If the river is too high to cross, you can also hike down to the hot spring up the side stream.
