Public land it sits in

On Wilderness Atlas →

This campground sits inside Ansel Adams Wilderness.

Each unit is published as a centre point and an acreage rather than a boundary, so this section stands it in for a circle of the same area. Whether a campground is inside, and how far it is from one it is outside, are both approximate.

Natural features

The campground is forested with lodgepole pine, providing partial shade and a private setting. It sits at an elevation of 8,600 feet at the base of snow-capped, 11,059' Mammoth Mountain, a popular skiing destination. A cascading waterfall flows into one of the lakes. The mountains are abundant with wildlife, including black bear, mountain lions, mule deer, pine marten, pika and many species of fish and birds.

Recreation

The eastern Sierras are known for great trout fishing, and the 108-acre lakes are a prime location for it. Anglers can cast for rainbow, brook and brown trout while watching a waterfall tumble into the lake. The calm waters are also inviting for canoes and kayaks. Power boats must have electric motors. Several trails offer a variety of hikes nearby, including a 4-mile trail on Mammoth Mountain and two shorter nature trails along the lakes. Families enjoy attending educational programs scheduled throughout the summer.

Nearby

Mammoth Lakes Basin contains several additional popular lakes to explore for fishing and boating, and Mammoth Mountain Ski Resort offers year-round recreation. Visitors can also access the magnificent John Muir Wilderness nearby, which stretches 100 miles along the crest of the Sierra Nevadas, a land of lofty snow-capped mountains, deep canyons and vast expanses of glacially-carved terrain. Abundant hiking and horseback riding trails are available.
