"This high-altitude marshland and mountain park on Honshu covers roughly 92,000 acres and is ringed by verdant slopes and an extinct volcano; it lies about 100 miles northwest of Tokyo and spans four prefectures (Fukushima, Tochigi, Gunma, and Niigata). Known for gentle terrain that suits hikers of varying abilities, the park features extensive trailheads, seasonal wildflower displays (June is especially recommended) and shuttle connections from nearby lodgings to deeper trails. The area retains cultural history as a site where yamabushi practitioners of Shugendō once stayed in intentionally austere communal huts, a legacy acknowledged by newer, more comfortable alpine accommodations. The main visitor season runs into autumn before winter closures." - Olivia Young
