Bathe at Goshiki Onsen
Niseko mountain range, Japan
Goshiki Onsen sits between the trailheads of Annupuri and Iwaonupuri, with sulfurous water and mountain air setting it apart from the resort hotels. The bathing areas include the Grand Bath and Karamatsu-no-Yu, with open-air soaking beside the surrounding peaks. Its name refers to the changing appearance of the water under different light and weather. Make it a destination in its own right or a warm finish to a day spent walking in the mountains.
