Kawayu
The hot spring resorts of Kawayu near Lake Kussharo and Akan Kohan at Lake Akan offer, surprise surprise, hot springs.
There are many excellent hikes in the region. In summertime at the Akan Kohan ski ground é¿å¯æ¹çã¹ãã¼å ´, there are two interesting short hikes, one 550m, the other 2.2km. The shorter one takes you to a ski slope with an excellent view of Lake Akan, its islands and the surrounding forest. The longer one starts off climbing about 900m up a ski slope before delving into the surrounding forest and taking you past a hot water creek 47 degrees, and several bokke ããã±, an Ainu word referring to hot mud caused by volcanism. Another hike from the Kawayu Onsen Visitor's Centre to Iwo-san 2.4km is a very flat and easy but extremely interesting one starting off in luxuriant forest on a moss path before petering out into desert-like scrub as you approach the poisonous vapours of Iwo-san.
