- Check-in 1pm / check-out noon
- Hazard: Deep natural lakes (main pond reported 30-135 ft in different sources) — scuba training platforms and submerged chain-link resting areas; cold-shock/hypothermia unlikely but depth is real

About this spring
Private hot-spring RV resort on the Malad River near Plymouth (historically 'Udy Hot Springs') — two natural mineral spring lakes: a ~2-acre ~97°F main pond and a warmer ~104°F soaking pond. One of the few warm-water inland SCUBA certification sites in the country. Fee: Private RV resort; day-use passes by arrangement — call ahead. Private — confirm day-use availability before driving out.
Belmont Hot Springs — historically known as Udy (or Uddy) Hot Springs and at one time operated as Camperworld — is a private RV resort on the thermally active Malad River bottoms about a mile southwest of Plymouth in northeastern Box Elder County. The property's centerpiece is two natural mineral spring lakes the resort reports at 97 and 104°F: the larger Main Pond covers about two acres, measures roughly 370 by 140 feet, and reaches about 30 feet deep at its south end, while the smaller, warmer pond is used more for soaking. A string of smaller named vents — Indian Pool, Morning Glory Hole and the Mud Pots — lies south of the main lake.
The warm, relatively deep ponds make Belmont one of the few inland hot-water scuba certification sites in the western United States. Two training platforms are installed in the main pond, visibility runs 5-15 feet, and the resort closes the lake to diving May through October when water temperatures peak. Day-use passes are available by calling the office.
Directions & trailhead access

Utah geothermal context
Utah's springs surface along the Wasatch Front fault system and across the western desert basins. Canyon sites like Fifth Water can flash-flood in storms and close under avalanche danger in winter; desert sites like Meadow involve long graded-road approaches through open range. Elevation changes of thousands of feet mean 'the weather' varies wildly by site.
What a resort site means here
A resort spring is a commercial operation: developed pools or tubs with controlled temperatures, changing facilities, and usually day-use fees or lodging packages. Expect posted rules (swimsuits, quiet hours, age limits), staff on site, and in many cases required reservations — especially on weekends and holidays.
Best time to visit
Year-Round (Best: May – October)Pool temperatures and access can change with weather and season. Outdoor ambient temperatures fluctuate significantly across Utah. Late spring through autumn offers the most comfortable road access.
