Spreading through the eastern end of Hokkaido, Akan National Park features volcanic mountains, dense forests of subarctic primeval trees, and three caldera lakes, including Lake Akan. The best place to stay in the park is Akanko Onsen, a small hot-spring resort on the edge of Lake Akan and home to some 2,000 residents. It makes a good base for active vacations ranging from fishing to hiking and from which to explore both Akan National Park and nearby Kushiro Marshland National Park, famous for its red-crested cranes. It also has a re-created Ainu village, with one of the best music and dance performances I've seen.
