Mammoth Lakes, California
Mammoth Lakes owes its network of natural hot springs to its volcanic past. Once upon nearly 800,000 years ago, a volcanic explosion laid the foundation for the network of hot springs that stretches from Bridgeport to Mammoth Lakes. Today, several commercial hot springs in the area are open to the public, including Benton and Keough. Plenty of undeveloped hot springs exist as well, like Travertine and Buckeye, but finding them will take a little legwork. Some of these sites are threatened with overuse, and not all of them are safe for dipping. So talk to locals and stop in at the Mammoth Lakes Welcome Center
for the full skinny.

Glenwood Springs, Colorado
The Glenwood Hot Springs Pool
is fed by the Yampah spring—one of the hottest natural hot springs in the world. The water from the spring is so hot (122° F to be exact) that it has to be cooled down for bathers. The 1-million-gallon main pool is kept at a balmy 90° F, and is perfect for the entire family. Adults looking for peace and quiet may want to retreat to the "smaller" 100-ft by 400-ft hot tub, which is cooled to a pleasant 104° F. Book an overnight stay at the Glenwood Hot Springs Resort or purchase admission to splash around for the day.

Bagby Hot Springs, Oregon
Nestled in Oregon's Late Successional Reserve Forest, Bagby Hot Springs
is a rustic escape from the hustle and bustle of modern life. Pay a small fee to park and then hike a 1.5-mile trail over river footbridges and beneath old-growth forest to the primitive cabins. Inside you'll find a number of whiskey-barrel style tubs and 8-ft-long, hollowed out cedar logs. The water is hot; the soak is free; the view is...primordial.

Hot Springs State Park, Wyoming
Tour Hot Springs State Park
and take in the steam- and snow-drenched landscape. Wonder at the majestic, free-roaming herd of buffalo. Traverse the swinging bridge across the Bighorn River. Then (thanks to a treaty signed with the Shoshone and Arapaho in 1896), you can also partake in the park's namesake. The hot springs' bath house is free and open five days a week, barring winter holidays. The soaking pool is maintained at an optimal 104° F.

Jefferson Pools, Virginia
If you're looking to soak in hot water and more than two centuries of American history, then few hot springs can best the Jefferson Pools. Owned and operated by the nearby Omni Homestead Resort
, the pools were named after Thomas Jefferson, who raved about the springs during his visit in 1818. The octagonal Gentlemen's Pool House was built in 1761 and looks it. But the 40,000-gallon pool features crystal-clear, untreated spring water so rich in mineral content that bathers nearly float. The Ladies' Pool House was added later and allows for separate bathing. Combined family soaks are also available during scheduled times.
