An entrance pass is not required to access Devils Postpile National Monument.
Other National Park Service sites may require an entrance pass or fee. Depending on your trip plans, an interagency pass may save you money.
Nearly all visitors must use a shuttle bus (with fee) to visit Devils Postpile. For those excepted from the shuttle requirement, Inyo National Forest charges an entrance fee to Reds Meadow Valley, which you must pay in order to drive to Devils Postpile.
Shuttle Bus Fees and Information
The Reds Meadow Shuttle Bus, operated by the Eastern Sierra Transit Authority, has provided transit service into the Reds Meadow Valley and to the Devils Postpile National Monument for over 30 years. Most visitors must ride the shuttle to access the Valley and Devils Postpile. Visit the shuttle bus information page for shuttle schedules and other information regarding shuttle bus logistics. Keep reading for a list of exceptions and exception vehicle fees.
Children age two and under ride free.
Well behaved, leashed and muzzled dogs are welcome to ride the shuttle. Muzzles are available for purchase in pet stores in Mammoth Lakes and at the Mammoth Mountain Adventure Center where shuttle bus tickets are sold.
Commercial tour operators or large groups should call Eastern Sierra Transit in advance at 760-872-1901 so they can be prepared for your visit.
Exceptions to the Mandatory Shuttle Bus
Vehicles meeting any of the following criteria may drive into the Valley (fee required):
Fees for Exception Vehicles or When Shuttle Bus is not Operating
If you drive to Devils Postpile, the US Forest Service charges a standard amenity fee (entrance fee) to enter Reds Meadow Valley. (This fee is also valid for Mono Lake South Tufa Reserve and the Ancient Bristlecone Pine Forest if visiting while the fee is still valid.)
Fees and Information for Bicycles
The fee does not apply to cyclists riding both into and out of the valley. Cyclists taking the shuttle out of the valley will have to pay the shuttle bus fee on the way out. Exact change is preferred to make the transaction go smoothly.
For visitors wishing to ride the road in, but not out of the valley, buses may carry up to three bikes on front-mounted bicycle racks. Biking off road is not permitted anywhere in the Reds Meadow Valley with one exception. Mountain biking is permitted on the Starkweather Trail only after the shuttle bus has stopped running for the season.
