Yunhai Hot Spring
Yunhai hot spring located in Nantou county, Renai township. From the parking spot to Yunhai hot spring, one-way distance is about 2.3km and it takes about 2 hours to get there. You will first pass Jingying hot spring, Jingying waterfall and climb up to the top of the waterfall and pass six sand retaining dams. This is very fun and challenging route, it requires many climbing and river trace to get there. It is also best to go during the dry season when the water level is much lower in order to have a hot spring. If possible, we strongly recommend you camp for a night.
After the first sand retaining dam, river trace up a little bit you will see second dam right away. Go to the left and up the iron ladder then go to left again use to rope to climb up. I suggest you bring one 10 meters rope to help with climbing because the ropes there are a bit old. After second dam, continue to river trace upstream you will meet the third dam. First, climb up from the left side using the rope and then to go right side, pass mini log bridge, and climb up using the rope from the right.
