Onuma Quasi-National Park
大沼国定公園
A lakeside park at the foot of the active volcano Mount Komagatake, with 126 small islets scattered across the lake. Strolling around the shore, sightseeing boats, and cycling are all delightful.
Onuma Quasi-National Park is made up of Lake Onuma, Lake Konuma, and Lake Junsai, formed by eruptions of Mount Komagatake. The lake holds 126 small islands, connected by more than a dozen small bridges. You can walk the island trails for 15-50 minutes, take a sightseeing boat for about 30 minutes, or rent a bicycle to ride around the lake (about 14 km). Mount Komagatake reflected in the water is beautiful, and the autumn foliage in October is especially lovely. In winter, when the lake freezes, you can try ice fishing and snowmobiling. Local specialties include Onuma dango and Onuma beef. Admission is free. From Hakodate, take the JR limited express about 25 minutes to Onuma-Koen Station, and the park is right at the exit.
