Belmont Hot Springs RV Park sits along the Malad River in Garland, Utah, blending mineral-rich geothermal pools with full-service camping and a unique warm-water scuba-diving experience rarely found in the western United States.

This northern Utah hot springs resort is just 85 miles north of Salt Lake City (about an hour and 15 minutes by car).

The scenic Malad River Valley wraps around it, with limestone terraces and open desert views.

The site was historically known as Udy Hot Springs. Over the years, it also ran as Camperworld and Retrailia RV Resorts. Today, it's a private RV park with day-use access for soakers and divers alike.

The resort is known for its two large mineral-water lakes, year-round soaking, full RV hookups, glamping accommodations, and warm-water scuba training and certification. The deep geothermal lake provides a diving experience rarely found elsewhere in the region.

So, are you ready to soak, dive, and unwind in Utah's high desert? Let me show you around.

Belmont Hot Springs Soaking Experience

At Belmont Hot Springs, visitors can soak in two large mineral-water lakes fed by natural geothermal springs.

The water rises through fractures in the limestone bedrock beneath the Malad River Valley. Heated deep underground, it reaches the surface through numerous natural vents. Source temperatures range from 93°F to 125°F (34°–52°C).

Watch the lake bottom, and you'll often spot streams of bubbles marking where hot water rises from below.

So what's the difference between the two lakes?

The larger lake covers about 2 acres and averages around 97°F (36°C). It reaches depths of approximately 135 feet, making it the resort's primary scuba-diving lake.

The smaller lake spans roughly 1 to 1.5 acres and stays warmer at about 104°F (40°C). Both lakes feature natural ledges along the edges that are perfect for sitting back and relaxing.

The mineral-rich water contains sodium, chloride, calcium, magnesium, and sulfate and has a mild sulfur odor. Strong spring flow helps continually refresh the water.

South of the larger lake, smaller geothermal features such as Indian Pool, Morning Glory Hole, and the Mud Pots add to the area's appeal. All water is eventually drain into the Malad River.

The larger lake is home to bluegill and channel catfish, while the smaller lake contains tiny fish commonly seen near the shoreline. Don't worry, they won't bother you.

Clothing is required throughout the resort, so don't forget your bathing suit.

Belmont stands out for scuba diving because students get to train in warm water. The diving lake runs about 30 to 35 feet deep, with visibility between 5 and 15 feet. That makes it a favorite for diver training, refreshers, and certifications.

Divers work with course providers rather than booking a set daily attraction. The smaller pond, meanwhile, stays open for soaking and swimming all year, with day-use available daily.

I like that you can also hike the terraces, explore the smaller natural springs, and watch wildlife along the river.

Want to soak more across Utah? Two nearby spots are worth a stop.

Crystal Hot Springs shares Belmont's fault-controlled origin and sits a short drive away. Homestead Crater Hot Springs, near Midway, lets you soak, swim, and even scuba dive inside a 55-foot limestone dome.

Planning to stay a while? Belmont has you covered.

The RV park offers full hookups at every site, with 30- and 50-amp electricity, water, and sewer. All sites are angled for easy in-and-out parking.

Prefer something cozier? Glamping rentals come with stylish décor, a comfy bed, and home-like comforts.

Guests get free showers and clean restrooms, a clubhouse for gatherings, coin-operated laundry, and WiFi across the property. The park is pet-friendly, too. Just keep your dog leashed, and no dogs in the springs.

If you'd rather sleep in town, lodging is available in Tremonton, about 12 miles south.
