Mountain groups

- Tokachi Volcanic Group — lies in the southwest of the park, north of the Yubari and Hidaka Mountains. It includes Mount Tokachi
These volcanic groups lie around a central highlands dominated by Mount Tomuraushi. The park is also known for its alpine meadows and remote backcountry.
