During the Shuttle Bus Season
Most visitors to the monument enter the monument and the Reds Meadow Valley by using the mandatory shuttle bus. Ticket purchasing and shuttle bus boarding occurs near the Mammoth Mountain Adventure Center which is located near Mammoth Mountain Main Lodge. The shuttle bus will take visitors to any of ten bus stops in the valley including the Devils Postpile and Rainbow Falls trailheads. For more detailed information on the shuttle bus and how to travel to the monument during the shuttle bus operating season, visit the shuttle bus page.
For through-hikers, backpackers, or other visitors without vehicles needing to get to Mammoth Lakes:
Outside of the Shuttle Bus Operating Season
When the Devils Postpile/Reds Meadow Shuttle Bus is not running, you may drive your vehicle into the valley. Keep in mind that the road is narrow, steep, and descends almost 1,500 vertical feet from the Minaret Vista Station, where visitors pay a standard amenity fee of $10. Parking lots usually fill up by 11:00 a.m. Planning your trips to arrive before 10:30 a.m. or after 2:00 p.m. will make it easier to find parking.
Due to the extremely limited parking available during busy weekends in the valley, a complimentary intervalley shuttle will run between parking areas at Reds Meadow Resort and Devils Postpile from 10:00 a.m. to 3:30 p.m. on Saturdays and Sundays. The Devils Postpile parking lot will be closed during this time and visitors will be directed to park at Reds Meadow Resort and take the bus to Devils Postpile.
Vehicles Longer than 25 Feet Visiting Devils Postpile
There is currently a vehicle length restriction of 25 feet on the Devils Postpile spur road. This does not apply to the entirety of the Reds Meadow Road and larger vehicles may still access USFS campgrounds and facilities. There are a few options for visitors with long vehicles wishing to visit Devils Postpile.
Recreational Vehicles: For visitors with recreational vehicles or vehicle/trailer combinations longer than 25 feet that wish to camp in the Reds Meadow Valley, there are several U.S. Forest Service campgrounds all within 5-6 miles of Devils Postpile that can accommodate larger RVs. Visit www.fs.usda.gov/inyo for more information. Once you find a camping spot, the shuttle bus is free for in-valley transit. You can take the shuttle from your campground to Devils Postpile or the Rainbow Falls Trailhead for free. There is not adequate parking for large RVs at the monument after the shuttle bus season.
Commercial Tours: All commercial tours must apply for a commercial use authorization. If the commercial tour will be traveling in a vehicle longer than 25 feet, you must contact Eastern Sierra Transit Authority to arrange transportation into the monument for the tour. If the tour is arriving in a vehicle less than 25 feet, you still must apply for a commercial use authorization.
Educational Tours and Non-Profit Groups: If you are visiting Devils Postpile as part of a non-profit or educational tour, please visit the special use permit page to apply for a special use permit.
Regional Transit Options
The area surrounding Devils Postpile is relatively easy to navigate using public transit. There are two primary transit providers.
Eastern Sierra Transit provides bus service to the monument (fee service), within the Town of Mammoth Lakes (free), and along the Sierra Crest from Ridgecrest to Reno (fee service).
Yosemite Area Regional Transportation Service (YARTS) provides transit from the Mammoth Area into Yosemite and to the west side of the Sierra Nevada for a fee.
Backpackers: Combining the Reds Meadow/Devils Postpile shuttle with the free routes in Mammoth Lakes and/or the YARTS buses is the easiest way to get from the monument/Reds Meadow Valley to town or to Yosemite.
