Devil's Postpile National Monument, established in 1911 by presidential proclamation, preserves a rare sight in the geologic world: massive basalt columns towering 60 feet high and displayed in unusual symmetry. A dramatic waterfall, 101-foot-high Rainbow Falls, is also in the park.

Devil's Postpile is also rare in that it is one of relatively few preserves under National Park Service jurisdiction that is dog-friendly. Pets must be leashed at all times and muzzled when riding the shuttle bus, which is mandatory with a few exceptions. Muzzles are available at local pet stores in Mammoth Lakes and at the Mammoth Mountain Adventure Center near the shuttle bus boarding area.

GETTING THERE:
From U.S. Highway 395, drive 10 miles west on State 203 to Minaret Vista and then another eight miles on a paved, steep mountain road. Please note that this road is single lane for approximately three miles.

The mandatory Reds Meadow Shuttle typically runs from mid- to late June and through Labor Day (first Monday in September). Visitors not meeting one of the exceptions must ride the shuttle bus.

When buses are not running, visitors must pay a standard amenity fee at the Minaret Vista Station or show an interagency pass at the Minaret Vista Entrance Station.

Visit the Monument's website for more information about operating hours, shuttle service, exceptions to mandatory shuttle requirements and fees.

Shuttle bus tickets can be purchased at the Mammoth Mountain Adventure Center located in the Mammoth Mountain Ski Area Gondola Building adjacent to the Mammoth Mountain Inn at the top of Highway 203. Reservations are strongly encouraged.
