Mt. Hakuto Nature Trail
This trail is easily accessible from Akanko Onsen. From Akankohan National Ski Area, it is a relatively easy 1.5-hour trek from the bottom of the ski field to the Mt. Hakuto Observatory (800 m). In spring and summer, the ski field turns into a vast meadow of wildflowers. In autumn, the leaves of the conifers along the trail turn an array of fiery colors.
The trail passes a stream fed with water from a natural hot spring, as well as bubbling mud pools known as bokke. Bokke are the result of geothermal activity, and there are several of them scattered throughout the Lake Akan area. The pools bubble and gurgle, and are usually heard before they are seen.
About 800 meters up the mountain, there is an observatory with views of Lake Akan, Mt. Oakan, and Mt. Meakan. Despite the altitude, the ground temperature around the observatory is relatively warm. This is because of geothermal activity, which prevents snow from building up on the ground around the observatory in winter and enables moss to grow.
