It is the only place in Japan where the marimo of an appreciable size is formed.
The park can be divided into two general areas, Kawayu and Akan.

Mount Iō and Onsen Kawayu offer natural hot springs and sulfur
fumaroles. Around Lake Kussharo, a crater lake, are the Bihoro
Pass, Mount Mokoto and Mount Nishibetsu. In the lake, the Wakoto
Peninsula is an area with uniquely adapted soil and high
temperatures, and Mashū Lake is a crater lake, one of the
clearest lakes in the world, with visibility up to 40 meters.

The Akan caldera is a large volcanic caldera more than 20 km in
diameter. Emerging from the interior of the caldera is the Akan
Volcanic Complex, which includes the highest mountain in the
park, Mount Meakan.The lake also has boiling mud, called bokke.
Churui Island is one of four islands on the lake and the site of
the Marimo Exhibition and the Observation Center. Lake Onneto is
at the foot of Mount Meakan. Nearby there is a waterfall of hot
water, Onneto Yu-no-taki. From Sokodai, one can observe Lake
Penketo and Lake Panketo. The observatory of Mount Hakuto, Mount
Kikin, Tsurumi Pass, and the observatory on the shore of Lake
Akan offer panoramas of the surrounding countryside. On the Akan
