Lelegu Hot Spring (中文版：樂樂谷野溪溫泉) is a series of wild hot springs in Nantou, Xinyi Township. It takes about 2 hours to hike to Lelegu Hot Spring. The first half of which is on the same route to Yunlong Waterfall. Once down at the hot spring, there are several outcrops where hot water is coming out of the rocks over a span of a few hundred meters. It can only be easily reached in the winter time, when the water levels are low.
Unfortunately, according to the park service the trail is closed until February 2017 due to a landslide.
