There are about 8 miles of trails in Devils Postpile National Monument. The trails offer a variety of opportunities for all fitness levels. Expanding your hiking outside the boundaries of the Monument will take you into the High Sierra of the Ansel Adams Wilderness. If hiking with your pet, make sure it is on a leash at all times within the Monument. All of the following distances are from the Devils Postpile trail head.
From U.S. Highway 395, drive 10 miles west on S.R. 203 to Minaret Vista and then another 8 miles on a paved, steep mountain road. Please note that this road is single lane for approximately 3 miles. Most visitors must park at the Mammoth Mountain Ski Area and use the mandatory shuttle. The shuttle bus operates from mid-June through the Wednesday after Labor Day.<br /><br /><br /><br />Exceptions to the shuttle system are those visitors who drive into the Reds Meadow Valley before 7:00am or after 7:30pm, or who are overnight guests of Reds Meadow Resort, who are camping within the Reds Meadow Valley, who are hauling stock trailers, whose vehicles are carrying small watercraft for use in the lakes, or who can provide proof of physical handicap.<br /><br />Source: National Park Service
