The Mihara Volcano hiking course is attractive for its powerful active volcano and otherworldly scenery. You can enjoy the steam rising from the huge crater with a diameter of about 300 meters and a depth of about 200 meters, as well as the black desert, which looks like it's not on Earth, called the "back desert". The scenic view spreads out from the promenade where even beginners can walk with peace of mind, and you can also experience Japan's only desert while trekking.
