Devils Postpile National Monument

Devils Postpile National Monument

Reds Meadow Valley

The Reds Meadow Valley, although closed to vehicles in the winter, is available to backcountry skiers and snowshoers. This is a true winter wilderness experience and travel into the valley can be hazardous. For those with proper avalanche safety skills and physical conditioning, however, the valley offers outstanding touring and provides a gateway to the High Sierra backcountry. There are NO facilities available in the valley in the winter and all travelers should be prepared to be self sufficient.

Snowmobiles are allowed on the Reds Meadow Road, but are not permitted on the road to Devils Postpile or anywhere within the boundaries of the monument. Please be respectful of this regulation.

Remember that avalanches are frequent on the Reds Meadow Road. Traveling alone is not recommended in the winter months due to the potential avalanche hazard. Anyone traveling into the valley should be equipped with and know how to use minimum safety equipment, including the following:

* Avalanche beacon
* Collapsible shovel
* Avalanche probe
* Extra food and water
* Extra warm clothing
* Ski/snowshoe repair kit

Winter travel in the valley can be a beautiful and rewarding experience. Research your trip ahead of time, checking the weather and avalanche forecasts. Check with the Eastern Sierra Avalanche Center for updated reports throughout the winter.



The closest commercial airport is in Reno, Nevada. From Reno, drive south on U.S. Highway 395 for approximately 3 hours (170 miles) to State Route 203.


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 end of September.

Exceptions to the shuttle system are those visitors who drive into the 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.

All visitors to the area, whether they take the mandatory shuttle bus or drive their personal vehicle, must pay a transportation fee. The fees are as follows: $7 for adults, $4 for children (3 to 15 years of age), or a $20.00 car cap for groups who are staying overnight in Reds Meadow Valley. Season passes are available for $35.00. Golden Passports, America the Beautiful, and National Park Passes are not valid for this transportation fee under the Federal Lands Recreation Enhancement Act. For more about this fee, click here.

Shuttle bus tickets can be purchased at the Forest Service Adventure Center located in the Mammoth Mountain Ski Area Gondola Building adjacent to the Mammoth Mountain Inn at the top of Highway 203. Buses run every 20 or 30 minutes.


For those visitors keen to bike down to the Postpile, bicycles are allowed down the road free of charge. If, however, visitors choose not to ride back out of the Valley and opt to use the shuttle instead, they must pay the transportation fee. The buses will transport bicycles if space is available.
