Inside the national park, in the valley of the Yokoyu-River, is the Jigokudani Monkey Park (地獄谷野猿公苑, Jigokudani Yaen Kōen) located. The name of the park comes from a large population of wild Japanese macaques, who retreat to the valley in winter.

A highlight for visitors is swimming in the warm waters of the onsen (Hotsprings). Especially at warm temperatures and without snow the monkeys do without a warming bath.
