Mount Adams Wilderness

Mount Adams Wilderness is a nature reserve in the Cascade Range spanning about 47,700 acres of varied terrain. It includes subalpine forests, alpine meadows, and volcanic formations within the Gifford Pinchot National Forest.

The area gained protected status as a wilderness area in 1964, a key step in preserving this landscape. This designation helped shield the region from commercial development and safeguard its ecological character.

The area holds deep spiritual meaning for the Yakama Nation and other Indigenous peoples who have practiced their traditions here for generations. This mountain landscape remains central to their ceremonies and cultural practices today.

Hikers should prepare for variable weather conditions, as snow blocks many trails until early summer arrives. Permits are required for overnight camping, and planning activities with these seasonal conditions in mind is important.

The area contains 21 miles of the Pacific Crest National Scenic Trail, a major route for long-distance hikers. Potato Hill within the wilderness works as a weather monitoring station, collecting data for regional forecasts.
