Campground details
Setting
Twin Lakes Campground sits at 8,600 feet in the eastern Sierra Nevada Mountains at the base of Mammoth Mountain. Shaded by lodgepole pines, the large facility is split across two sections around the 108-acre water body. Sites include picnic tables and campfire rings, with flush toilets and drinking water available. Anglers fish for rainbow, brook, and brown trout below a tumbling waterfall, while non-motorized boats, canoes, and kayaks navigate the lake. An on-site general store provides boat rentals, basic supplies, and pay showers, with hiking trails leading into the forest.
Getting there: The campground is 320 miles north of Los Angeles and 180 miles south of Reno, Nevada. Follow U.S. Highway 395 to the junction of State Highway 203. Turn west on 203 and drive 7 miles through the town of Mammoth Lakes. Highway 203 becomes Main Street, and then becomes Lake Mary Road, which leads to the Lakes Basin. Continue on Lake Mary Road to the Twin Lakes cutoff.
