Lake Haruna hikes (榛名湖)
Lake Haruna is a large caldera lake located about 20km northwest of Takasaki city in central Gunma Prefecture. The lake offers camping, boating, and fishing during the warmer months, and ice fishing during the off-season. The waters are ringed by a series of wonderful rolling peaks, making it an ideal place to get those leg muscles into shape. The hikes featured here should keep you occupied for a few days.
