The Pacific Crest National Scenic Trail passes north/south through the wilderness, which is known for its many lakes and views of four nearby volcanoes: Mount Adams, Mount Hood, Mount St. Helens, and Mount Rainier. It is also known to hikers for an intense population of mosquitoes throughout the summer. Other major trails in the area are Indian Heaven Trail and the Cultus Creek Trail, which climbs up the east side of Bird Mountain, and Lemei Trail which traverses up the east side of Lemei Rock and passes by Lake Wapiki. In late fall, the huckleberry bushes provide berries as well as intense orange color in some years.
