Deogyusan National Recreational Forest (국립 덕유산자연휴양림)

Deogyusan National Recreational Forest sits inside Deogyusan National Park in Muju, on the western slopes of Hyangjeokbong (1,614 m). It's one of Korea's larger recreational forests, with a network of marked trails ranging from a one-hour stream loop to a four-hour ascent toward the Hyangjeokbong upper ridge. Forest Service cabins and group lodges are bookable through the official portal, and the elevation means the leaves turn a week or two later than the lower-altitude forests in the region — extending the autumn foliage season into early November. The Muju Resort and the Tageosak observatory are a short drive away. Reservations essential year-round. Pair with Muju Gucheongdong tourist zone.
