The Mount Thielsen Wilderness is a wilderness area located on and around Mount Thielsen in the southern Cascade Range of Oregon, United States. It is located within the Deschutes, Umpqua, and Winema National Forests. It was established by the United States Congress in 1984 and comprises 55,100 acres (22,300 ha).
Mount Thielsen Wilderness ranges in elevation from 5,000 feet (1,500 m) above sea level to 9,182 feet (2,799 m) at the summit of Mount Thielsen. The mountain was carved by glacial activity and is sometimes referred to the "Lightning Rod of the Cascades." To the south of the wilderness is Crater Lake National Park. The rest of the wilderness consists of flat and moderately rolling hills, which change to very steep and sharply dissected ridges toward the crest of the Cascade Mountains.
Primary recreational activities in Mount Thielsen Wilderness include camping, hiking, wildlife watching, and rock climbing. There are approximately 78 miles (126 km) of hiking trails in the wilderness, including a 26-mile (42 km) portion of the Pacific Crest Trail.
