The Tahoe Rim Trail Association is a volunteer, non-profit 501(C)(3) organization established in 1981 to plan, construct, and maintain the Tahoe Rim Trail. This 165-mile, twenty-four inch, single-track trail is open to hiking, equestrians, and mountain biking (in most areas). The trail encompasses the ridge tops of the Lake Tahoe Basin, crossing six counties, and two states. The Tahoe Rim Trail overlaps with approximately fifty miles of the Pacific Crest National Scenic Trail. Our mission is to maintain and enhance the Tahoe Rim Trail system, practice and inspire stewardship, and preserve access to the natural beauty of the Lake Tahoe region.
