General Information

Description - 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.

Location - 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.

Report: Went to Mammoth Lakes this summer to visit my daughter who has lived there for 4 years. Wonderful, beautiful place! Lot's to do. InYo National forest - Hiked Agnew Meadows Wildflower Walk, beautiful! Hiked to Devils postpile and Rainbow Falls, breathtaking and historical! We took the dog as a lot of people do! Went to Yosemite for a day! Awesome! Was a great 50th birthday present as I had always wanted to go there and experience the beauty we have on this earth and this is the place to go. Went horseback riding close to Lake McGee. Canoed on Lake Mary. Had coffee that morning with a beautiful view of the Minnerets! Met some nice people in the 6 days I was there! Awsome trip, recommend for anyone to go there. The Sierra Mountain area is definately God's country! I recommend this trip to anyone! A good place for lunch in Mammoth would be Berger's (Burgers?). Had a great veggie burgers! Mammoth is a neat town. Also went to a beer festival in Mammoth. It was awsome, saw Jesse James from Monster Garage!
