From the Hokkaido World / Places
Ōnuma Quasi-National Park
Ōnuma offers lakes dotted with islands beneath Hokkaido Komagatake, a gentler landscape break near Hakodate. Lakeside cycling and boating offer different ways to see the volcanic terrain.
Walk or cycle around Ōnuma to watch the mountain appear between islands and water. The ponds formed when volcanic mudflows from Komagatake blocked low ground, so the calm scenery has a clear volcanic origin. A boat changes the angle of view when services run.
What to look for
Small islands scatter across Ōnuma and neighbouring lakes.
Hokkaido Komagatake rises behind the water.
Birch and maple woods frame the lake margins.
Useful to know
Choose a lakeside walk or cycle according to the time you have.
Check seasonal boating and route conditions before planning around them.
