HOURS OF OPERATION
Fall 2016: The Reds Meadow Valley road has reopened after a mudslide temporarily closed the road. Visitors should take care as there may be debris and rock on the road. As a reminder, there is no overnight parking or camping in the Valley after October 15. There is no potable water in the valley and vault toilets are available at Devils Postpile and Agnew Meadows. Visitors should expect delays along the road while crews complete necessary culvert clearing and hazard tree removal. Visitors should also plan that the road may close at any time due to rain or snow.
Monument Hours: Devils Postpile National Monument and the Reds Meadow Valley are open 24 hours/day 7 days/week during the operating season. If planning a trip in June, September, or October, please check the website for up to date weather and closure information. The monument will close temporarily if winter weather arrives early.
Ranger Station Hours: The ranger station is closed for the season.
Campground: The Devils Postpile campground is closed and will reopen for the 2017 season. Please check back for an opening date.
Trails and Day Use Areas: In the winter, the monument is open for recreational use but no amenities are available. Visitors can only access the monument on foot, ski, or snowshoe; and must be self-sufficient for backcountry winter travel.
Overnight Parking: During the shuttle bus operating season, visitors who are exceptions to the shuttle bus and are backpacking may use the overnight hiker parking just outside the monument boundary. There is a 1/4 mile walk from there to the trailhead along a trail. Shuttle bus users should leave their vehicle at the shuttle bus parking area at Mammoth Mountain. There is no charge to park your vehicle overnight. Please do not leave any food or scented items in your vehicle when leaving it overnight. Lockers are available at Mammoth Mountain Main Lodge. After shuttle bus operation, backpackers may drive into the monument. There is no overnight parking in the Reds Meadow Valley or Devils Postpile after October 15. Backpackers need to arrange for a shuttle or taxi or be prepared to hike out. The road will not be plowed after October 15.
Backpackers: If your trip starts while the shuttle bus is operational and ends after the shuttle bus season, please notify the staff at the Minaret Vista when you arrive. You will be able to drive into the valley. You must provide your wilderness permit as proof of your trip plan and must pay the standard amenity fee.
