Devils Postpile National Monument is located in the heart of California's Eastern Sierra. As such, a wide variety of recreational activities is available in the region. Within the Monument's nearly 800 acres, visitors can explore the area's unqiue geology, take a day-hike along the John Muir or Pacific Crest trails, or simply enjoy a meal in our day-use area alongside the Middle Fork of the San Joaquin river.  From camping, backpacking, and day hikes to fishing, photography, and horseback riding, there's something to do for everyone!

The fall is a beautiful time of year in the Sierra, but snow can come at any time.

While planning your upcoming visit, it is important to remember that Devils Postpile National Monument is only open during the summer months.

Although opening dates can vary depending on snow conditions, the Monument usually opens in mid-June. By mid to late October, early winter storms in the High Sierra typically begin to cover the area with a white blanket of snow. For the next seven months, the Monument will lie buried beneath the snowpack until the spring melt wrestles the area from winter's grasp.
