It's a 3½-hour hike from Bettōdeai to this basic mountain lodge, which is usually packed at the height of the midsummer hiking season, when you'll get about one tatami mat's worth of sleeping space in the main hall. Otherwise, bare-bones camping and cabins are available. Vistas are stunning and reservations essential.
