Mount Washington Wilderness, Wilderness area in Cascade Range, Oregon, United States.
Mount Washington Wilderness is a protected wilderness area in the Cascade Range of Oregon, covering land across two national forests. The terrain shifts between old-growth forest, open mountain meadows, and volcanic features such as cinder cones and hardened lava fields.
The area was designated as an official wilderness in the 1980s and added to the US National Wilderness Preservation System. Before that, the land had long been shaped by volcanic activity, which left behind the lava fields and cones still visible today.
The Mount Washington Wilderness sits along the Pacific Crest Trail, a long walking route that runs from Mexico to Canada. Many visitors pass through as part of a longer journey, which gives the place a steady flow of through-hikers alongside day visitors.
Before heading out, it is worth checking whether a permit is required, as rules can vary by season and zone. Bikes, motorized vehicles, and drones are not allowed anywhere in the area, so planning your gear accordingly will save time at the trailhead.
Belknap Crater, a volcanic cone made of ash and lava particles, rises above the surrounding land and is visible from several trails. The lava field around it is one of the youngest in the region, and its surface still looks raw and barely touched by time.
