Hot springs have long been pilgrimage sites for people seeking the healing powers of a long soak in natural, mineral-filled waters. For your own transformative plunge, here are four hot spots to check out this winter within a short drive of Park City.

Crystal Hot Springs

Honeyville, Utah  crystalhotsprings.net
Best known for having the highest mineral content in the world at 46,000 mg/l, the three hot tubs, Olympic-size pool, main soaking pool, and kid pool area all range 120–134 degrees. Two 365-foot hydro-tube water slides are open year-round and heated by submerged copper tubing in the hot spring, making it a great place for families to find some warmth in the winter months. No lodging or campsites are available.

Homestead Crater

Midway, Utah  homesteadresort.com
This one-of-a-kind geothermal spring is found in a limestone dome that is 55 feet tall, with an opening at the top to let the daylight and fresh air in. Formed over 10,000 years ago, the 65-foot-deep hot springs stay at a remarkably warm temperature year-round, making it an ideal place to get a scuba diving certification, do some paddleboard yoga, or just take a relaxing soak. Make it a weekend getaway by booking a room at the adjoining Homestead Resort.

Maple Grove Hot Springs & Retreat Center

Thatcher, Idaho  maplegrovesprings.com
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.

Mystic Hot Springs

Monroe, Utah  mystichotsprings.com
High levels of calcium carbonate in the water make these springs nearly odorless. Beautifully clean water gives way to a pleasurable soak in either a vintage cast-iron bathtub or one of two concrete pools, ranging in temperature from 100 to 110 degrees. The views are also abundant here, with hillside soaking areas that overlook the valley. Spa services are available by appointment, including massages and hypnotherapy. You can also stay overnight in an authentic pioneer cabin or a funky converted school bus.
