The Trinity Alps mountain range in the northwest corner of California forms a rugged divide, tucked between the Coast Ranges and the Cascades in a half-million acres of wilderness. Nearby Whiskeytown National Recreation Area, Russian Wilderness, and Castle Crags Wilderness all offer miles of trails and recreation areas to explore. The fifth edition of this classic hiking guide, in print for more than 25 years, has been completely revamped and now covers not only trails and cross-country routes in the Alps but in the nearby recreation lands. It contains descriptions of 48 of the best day hikes and backpack trips, and has all-new maps and elevation profiles for each specially selected hike. Over 600 miles of trail and cross-country routes are covered in this most comprehensive recreation guide to the area.
