After all of your Mammoth outdoor adventures, your body will inevitably be tired. Mammoth Lakes is situated on the edge of an active volcano, which means one thing—hot springs.
Water is heated in magma chambers deep below the earth’s surface and bubbles up in places around the Long Valley caldera just 10 minutes south of town. Locals built soaking pools around the valley in the 1970s and many of them are still maintained today.
Runners, skiers, off-road enthusiasts, and naked philosophers frequent the hot springs. Drive east on Benton Crossing Road and explore the dirt road turnoffs to find a tub, or pick up a copy of the hot springs guidebook at a local bookstore or gas station.
