A Guide to Mammoth Lakes


Much of the Mammoth Lakes area, on both sides of the Sierra Crest, is on Inyo National Forest land. A small but prominent exception is Devils Postpile National Monument, west of the Sierra Crest, which is administered by the National Park Service. The area's campgrounds generally close during September and October for the winter and reopen for the season (subject to snowpack) from April through June.

Devils Postpile National Monument

Devils Postpile Campground opens for the season around mid-June and closes in mid-October. There are 21 campsites, first-come first-served (no reservations), and they cost $14 per night. There are restrictions on summer driving to Devils Postpile.
