Baker Hot Springs
Three small concrete tubs in Utah's West Desert northwest of Delta, fed by springs at Fumarole Butte that emerge at about 180°F. Visitors mix in cold water through PVC pipes to set the temperature, and each tub fits only a few people. It is free.

Belmont Hot Springs RV Park
An RV park near Garland in Box Elder County built around two natural hot spring lakes, listed at 97°F and 104°F and also known as Udy Hot Springs. A hot springs access pass is sold to non-campers, and scuba diving is offered October through May by reservation. Pets are welcome in the park but not in the springs.
Fifth Water Hot Springs (Diamond Fork)
Several soaking pools along Fifth Water Creek in Uinta-Wasatch-Cache National Forest, beside a series of waterfalls, reached on foot from the Three Forks Trailhead on Diamond Fork Road. Visit Utah lists the soaking pools at about 100-102°F. The Forest Service warns that harmful bacteria may be present and advises not dunking your head and showering after soaking.

Gandy Warm Springs
A large warm spring, about 81°F, pouring nearly 9,000 gallons a minute out of the base of Spring Mountain in Snake Valley near the Nevada line. Visit Utah describes a lower pool that fits about a dozen people, with a small cave under a waterfall, and a more private upper pool about 50 feet up the hill. The site is on BLM land with no facilities, and the nearest services are about 30 miles away.

Meadow Hot Springs
Travertine spring pools in a farmer's field west of Meadow, south of Fillmore, on private land the owner keeps open to the public. Visit Utah describes two pools, the deeper one around 100°F with rock shelves, and says the owner built a walking trail and fence. Posted rules require swimsuits and ban alcohol, and visitors are asked to clean up.

Saratoga Hot Springs (Inlet Park)
Three natural pools near Utah Lake, reached by a city-built path from the Inlet Park parking area in Saratoga Springs. The pools reach about 109°F and have muddy bottoms. Visit Utah notes swimsuits are required, alcohol is not allowed and the springs close daily at 10 pm.

Veyo Pool
A spring-fed swimming pool in a basalt canyon in Veyo, north of St. George. Spring water enters at about 96°F and cools to the high 80s in the pool. The $18 canyon pass also covers a bolted climbing park and crawdad catching, and the pool is open May through October.
