Which Lakes in the Lakes Basin Are OK For Swimming?

Fortunately, all lakes in the Mammoth Lakes Basin welcome visitors looking to do some swimming. So it’s all right to plan your swimming and water activities in Twin Lakes, Lake Mary, Lake Mamie, Lake George, and Horseshoe Lake, as long as the weather is agreeable enough.

Horseshoe Lake, in particular, is a great option for families. It has a beach where you can launch kayaks or paddleboards. As no motorized boats are allowed in Horseshoe Lake, the area is especially safe for swimming.

The other lakes are easily accessible by car via Lake Mary Road. Just keep an eye out for fishermen and boaters while you’re swimming, as the lakes in the Mammoth Lakes Basin are multi-use.

Turn west on 203 and drive 7 miles through the town of Mammoth Lakes. Highway 203 becomes Main Street, then Lake Mary Road, which will lead to the Lakes Basin. Continue on Lake Mary Road to the Coldwater Campground cutoff on the left.
