Climate

Devils Postpile National Monument is located at 7,560 feet above sea level just west of the Sierra Nevada crest. As such, it experiences typical summer weather in the Sierras. Afternoon thunderstorms are possible in July and August. Daytime temperatures can range from the mid-70s to mid-80s (degrees Fahrenheit). Evening temperatures can drop into the low 40s (and even the low 30s in the months of September and October).

Visitor information

Get in

Due to winter conditions in the mountains the monument is open only during the summer season. Opening dates vary depending on snowfall, but in 2017 the monument opened to visitors on July 21. It is typically open well into October. Outside of that time access by car is not possible, although visitors traveling by ski or on foot may still be able to enter the park.

By air

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

By car

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. This road is single-lane for approximately 3 miles.

During peak visiting time, there is a mandatory shuttle bus. You cannot enter the park by car when the shuttle is running. It runs for a fee from season opening to early September. It may also run thereafter; for example, in 2019, it ran on a complimentary basis for shortened hours until mid-October, but not for the remainder of the season. (Unfortunately, the National Park Service's websites can have contradictory information, hotels may have outdated information, and the Monument's phone number does not always connect, e.g., on weekends and off season. Prepare for all possibilities and to inquire at entry.)

To use the shuttle, park at the Mammoth Mountain Ski Area. In addition to those who visit when the shuttle is not running, visitors who meet any of the following criteria do not need to use the shuttle:

• Visitors driving into the Valley before 7AM or after 7:30PM (hours differ when shuttle hours change).
• Visitors who are overnight guests of Reds Meadow Resort.
• Visitors who are camping within the Reds Meadow Valley.
• Visitors who are hauling stock trailers
• Visitors whose vehicles are carrying small watercraft for use in the lakes.
• Visitors who can provide proof of physical handicap (shuttle buses are not ADA compliant).

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.

By bicycle

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 shuttle buses are equipped to transport bicycles.

By foot

The Pacific Crest Trail (PCT) is a well known trail that extends along the West coast of the United States, from Mexico to Canada. It passes through California, Oregon, and Washington State.

Fees and permits

All visitors to the Reds Meadow Valley area, whether they take the mandatory shuttle bus or drive their personal vehicle, must pay a fee. The fees are as follows (2021):

• $15 for adults using the shuttle.
• $7 for children (3 to 15 years of age) using the shuttle.
• $10 per car.

Season shuttle passes are available for $75. Vehicle fees are waived for Golden Passport and National Park passholders (shuttle fees are paid to Eastern Sierra Transit, not the National Park Service, and cannot be waived). Fees are valid for the duration of the visit.
