Coldwater Campground is a campground located in the Mammoth Lakes area of the High Sierra in Mono County, California. Lake Mary is the largest and the most developed of the eleven lakes in the Mammoth Area. The campground is located along Coldwater Creek, which feeds water into the scenic Lake Mary.
The campground is quite popular due to its location on the mountain and proximity to Lake Mark. The lake offers tremendous fishing and opportunities for hiking and enjoying the picturesque scenery. The fishing at Lake Mary features Rainbow, Brown and Brook trout and on more than one trip, my evenings were spent watching sunsets while fly fishing. The peak season is from late May to early September each year.
The campground offers access to many nearby activities including Devils Postpile, Reds Meadow,, Rainbow falls and Hot Creek. Two boat ramps and marinas allow for boating however the 10 mph limit on the lake keeps the lake angler friendly. Campsites typically share parking and the sites are reasonably flat. Tall pine trees offer shade from the high altitude sun.
This campground is in bear country and typically bears activity is fairly high. All food and scented items must be stored in the lockers. All trash must be disposed of in the bear proof trash receptacles. Do not store food, trash or scented items in your vehicle.
