The Mount Adams Wilderness along the west slope of Mount Adams offers an abundance of opportunities for hiking, backpacking, backcountry camping, mountain climbing and equestrian sports. Trails in the wilderness pass through dry east-side and moist-west side forests, with views of Mt. Adams and its glaciers, tumbling streams, open alpine forests, parklands, and a variety of wildflowers among lava flows and rimrocks. A Cascades Volcano Pass from the United States Forest Service (USFS) is required for activities above from June through September.
