These 100-year-old pools outside of Honeyville have an interesting history: during World War II, wounded soldiers were sent to rehab at these springs by President Roosevelt. Today, you’ll find there a large natural soaking pool, a steamy Olympic-size pool, and a hot pool with a cool waterslide.

You’ll feel like you’re on another planet when you walk into the massive limestone rock dome to access this 65-foot-deep geothermal pool, hovering around a constant 90 to 96 degrees, at the Homestead Resort.

Situated just across the Utah border and surrounded by the beautiful scenery of the Oneida Narrows Reservoir are four rejuvenating hot springs known as Maple Grove. With waters featuring 14 natural minerals to soak in, nearby hiking trails and canoe rides, and a focus on wellness and digital detox, folks can enjoy the health boost of being one with nature. There are plenty of overnight accommodations to extend your stay past a day trip, too, from furnished yurts to canvas tents.

Owned by artist Mike Ginsburg, a.k.a. Mystic Mike, this "best hippie hot spring"  features two soaking pools and eight bathtubs built into the red-rock landscape. Buy a daily pass, or spend the night in a restored pioneer cabin or a converted school bus; tent and car camping are also permitted.

Just over 180 miles from Park City is the kitschy town of Lava Hot Springs, Idaho, named for the mineral water pools there, ranging in temp from 102 to 110 degrees. Book a room at the Home Hotel.

Good things come to those who hike: upon completing the 2.5-mile walk from the trailhead on Diamond Fork Road, you’ll be rewarded with a variety of hot natural pools and scenic waterfalls. Don’t be alarmed if you happen upon nude bathers here—swimsuits, while required, are often considered optional.

The water in the three large soaking tubs at Baker Hot Springs can be very hot, but you can adjust the temperature via two hot- and cold-water ditches that fill the tubs. Volunteers perform all maintenance, so please pack out your trash.

These three crystal-clear pools have varying temperatures, with the largest being the hottest, at approximately 100 degrees. The pools are located on private property in Meadow, just south of Fillmore, but they’re open to the public. Please follow the posted rules.
