The Kawayu Visitor Center has informative displays about Hokkaido wildlife, landscape, and activities such as renting snowshoes and bear bells. There is some English-speaking staff and a free onsen foot bath nearby.
For a great experience, consider taking part in small museum activities, renting equipment for trails, and learning about the flora and fauna in the Akan-Mashu National Park. Avoid encounters with bears and make use of the snowshoe rental in winter.
