Coldwater Campground is located high in the eastern Sierra Nevada Mountains near the town of Mammoth Lakes, California. The surrounding national forest provides many opportunities for family fun, outdoor recreation and relaxation. Hiking, fishing, road cycling and picnicking are just some of the favorite activities available to campers.
Coldwater offers easy access to fishing for rainbow, brook and brown trout in Lake Mary. Major trailheads lead into the backcountry. Several interesting trails offer a variety of hikes, including the 5-mile Duck Pass Trail, which climbs the forested hillside behind the campground and passes several lakes before heading over Duck Pass to join the John Muir Trail.
Campsites are organized into two loops, with sites fairly close together and near either creek. Pressurized water spigots and flush toilets are provided throughout the facility, and there are picnic tables, campfire rings and bear-proof food storage lockers at each campsite.
This campground sits in a pine forest at an elevation of 8,900 feet. Large and small boulders are strewn about the campground. Coldwater and Mammoth Creeks run alongside the campsites. Crystal clear Lake Mary, one of several lakes in the Mammoth Lakes Basin, is nearby.
The Eastern Sierras are abundant with wildlife, including black bear, mountain lions, mule deer, pine marten, pika and many species of fish and birds.
Visitors can explore the magnificent John Muir Wilderness, which stretches 100 miles along the crest of the Sierra Nevada Mountains, a land of lofty snow-capped mountains, deep canyons and vast expanses of glacially-carved terrain. Hiking and horseback riding trails are abundant.
Coldwater Campground is 320 miles north of Los Angeles and 180 miles south of Reno. Follow U.S. Highway 395 to the junction of State Highway 203. Turn west on 203 and drive 7 miles through the town of Mammoth Lakes. Highway 203 becomes Main Street, then Lake Mary Road, which will lead to the Lakes Basin. Continue on Lake Mary Road to the Coldwater Campground cutoff on the left.
