Sometimes spelled 'Taisetsuzan', this is Japan's largest national park, consisting of several mountain groups, volcanoes, hot springs, lakes and forests. It also includes Asahi-dake, at 2290m (7557ft) Hokkaidō's highest peak. The park is spectacular hiking and skiing territory, but bear in mind that a few days are needed to get away from tourist areas.

If you have limited time, Asahidake Onsen is a good spot for a quick look at the park. Tokachidake Onsen is more remote and may be good for those wanting to escape the crowds (a key consideration in summer and early autumn). There are a couple of hikes on the more well-trodden trails here, but there are also many more routes leading to more remote regions if you have several days, or even a week, to spare.

Hiking and other information with some English-language text is available at tourist information offices in the larger towns and destinations.
