It takes about 10-15 minutes to walk from Yunokawa Onsen Street. The botanical garden is small in size and the main body is a small greenhouse. From the outside, it is a small glass house, like a small church. The main attraction is the outdoor monkey mountain with spa. The macaques enjoy it very much. If the water temperature is not enough, they will refuse to take hot springs. Some monkeys are bald because of hot springs lol.
