SEASONS AT DEVILS POSTPILE
Spring is not generally a long season in the Sierra. At Devils Postpile, it is the time that the meadows flood, the rivers swell, and everyone waits for roads to clear. Depending on the year, winter can hold on into June, dropping snow on nearby Mammoth Mountain until Fourth of July. But other years, the shooting stars start to bloom in early June, just as the water recedes from the meadows. Visitors in early June should check conditions often as road closures due to weather are not uncommon and typically opening dates are uncertain.
When the monument opens in mid-June, visitors can expect a relatively quiet experience with uncrowded trails, maybe a snow patch or two, and amazing water flows at both Rainbow Falls and Minaret Falls usually until at least Fourth of July weekend. After that, although the waterfalls are still full, but so are park trails, overlooks, and shuttle buses. The mandatory Devils Postpile/Reds Meadow shuttle bus typically begins operations in June (weather permitting) and runs through the Wednesday after Labor Day, which is considered the end of the summer season. In August, crowds peak, campgrounds are typically full during the weekends, and stream flows in the waterfalls diminish significantly. Although Rainbow Falls flows year round, it is most impressive in June and July. August, however, is typically the warmest month and crowds usually subside around the end of the month just before the last rush during Labor Day weekend.
Fall is a beautiful time to be in the monument, but the weather can be a bit unpredictable and parking lots fill quickly. A parking shuttle operates between Reds Meadow Resort and Devils Postpile on weekends to relieve parking congestion. Generally, days are warm and nights are cold through early October. Blue skies prevail, but winter storms are not far away. Visitors in September and October will enjoy fall color that typically peaks in early October. Be prepared for rapidly changing weather, particularly if visiting in October. The ranger station is usually open through Columbus Day weekend, weather permitting. The monument typically closes the last Sunday in October, however, winter storms tend to move this closing date up most years. Temporary closures due to weather are not uncommon in the fall. If you catch it on the right day, however, there is nothing better than a cool fall breeze rustling the aspen and cottonwood trees along the San Joaquin River.
This may seem an odd time of year to visit Devils Postpile since the road is closed and the only access is by ski or snowshoe. But winter use is growing and the Reds Meadow Valley is a beautiful and wild place in this season. Trips into the Reds Meadow Valley are not for novice backcountry travelers. No facilities exist in the winter and the only way out of the valley is to climb the 1600+ feet back to the Minaret Vista. For the experienced backcountry traveler, however, many great adventures await. Make sure you have an in depth knowledge of winter travel and basic avalanche safety equipment before journeying into the valley. Check with the Eastern Sierra Avalanche Center for current avalanche conditions, plan ahead, and it is best to not travel alone.
