Day hikes do not require a permit. Those going into the backcountry overnight must obtain a free permit at one of the visitor centers, the National Park Service Complex headquarters in Sedro-Woolley, or the Wilderness Information Center in Marblemount. In addition to the hikes discussed here, a small section of the famed Pacific Crest Trail, which runs some 2,650 miles from Mexico to Canada, goes through the park. For information on the entire Pacific Crest Trail, contact the Pacific Crest Trail Association, 5325 Elkhorn Blvd., PMB no. 256, Sacramento, CA 95842-2526 (tel. 916/349-2109; fax 916/349-1268; www.pcta.org).
