During the summer, Mammoth is to mountain biking what Mt. Everest is to climbing: There is no equal. The Mammoth Mountain Bike Park provides more than 70 miles of singletrack through the spectacular Eastern Sierra Mountains. New this summer are the X-Zones, featuring jumps, bumps, berms and rollers. Still think you're tough? Try the Kamikaze Downhill. Starting near the summit of the new Panorama gondola, this course may make you upgrade your training schedule. Don't know a derailleur from a doughnut? Mammoth offers guided tours, skill clinics rental packages and has Mountain Bike Rangers who keep you rolling along.
The resort, however, moves beyond fat-tire tyranny. Get high on Mammoth's 32-foot manmade Climbing Rock. Or channel Ansel Adams during a guided tour through the Ansel Adams and John Muir wilderness areas (Mammoth Ranger Station, 760-924-5500). Families will enjoy the Adventure Challenge rope courses located behind the Mammoth Mountain Inn and the horseback trails that wind along Mammoth Creek and the Sherwin Mountains (Sierra Meadows Ranch & Equestrian Center, 760-934-6161). And don't leave your boards home. You can often crank turns here well after Memorial Day. Or turn back the clock and visit a Mammoth icon, the Tamarack Lodge (800-237-6879; www.tamaracklodge.com), which has rightfully attracted mountain lovers for generation.
