- Located at the heart of the Inyo National Forest, Mammoth Ranger District is centered on the town of Mammoth Lakes. A multitude of recreation locations can be reached within a ten-mile drive of Mammoth Lakes. A ranger station, visitor center, and RV park lie just outside of the town. Opportunities for backpacking, camping, stock packing, boat launching, water play, and winter sports lie in the vicinity. The John Muir Wilderness can also be accessed from this Ranger District.
Recreation - Recreation opportunities in the Mammoth include but are not limited to camping, trailer and RV camping, stock packing, boat launching, water play, and winter sports. All lie within an easy drive of the town of Mammoth Lakes.
Climate - Deep snow often covers the middle elevations from December to May, but subzero temperatures are rare. Precipitation falls mostly between January and mid-May, but thunderstorms, rain and even snow can occur at any time of year.
Temperatures vary with elevation. In the summer, daytime temperatures often exceed 100 degrees F in the foothills, but seldom exceed 90 degrees at higher elevations. Even in the summer, backpackers in the high country can encounter nighttime temperatures in the low 30's, and occasionally even in the 20's. In any season, it is wise to bring clothing that can be "layered". Always include some kind of rain gear.
This ranger district centers on the town of Mammoth Lakes. It abuts the Sierra National Forest to the west and is bisected by US Hwy. 395.
