What Is the Utah Crater Soak & Swim Tour?

This tour offers a chance to relax in North America’s only year-round indoor geothermal hot spring. Found in Midway, Utah, the hot spring is a natural formation that has been warmed by geothermal activity over thousands of years—not volcanic but geothermal, with the water source located about two miles beneath the surface. The environment is a domed indoor crater that maintains a stable temperature of around 94°F, perfect for soaking regardless of the season.

Beyond the hot spring itself, the tour incorporates visits to several local attractions, giving you a snapshot of Midway’s charm. These include a stop at the Swiss Village Zermatt Resort, where you can enjoy chocolates and baked goods, as well as the Midway Chocolate Factory and, weather permitting, an Artesian Cheese and Dairy Farm. The tour is designed for flexibility, with departure times ranging from morning to late afternoon, based on availability and weather conditions.

The Experience Itself: What You’ll Do and See

The core of the tour is the 45-minute soak in the indoor hot spring. We loved the way the warm, mineral-rich waters provided a soothing experience that’s perfect for relaxing muscles after hiking or sightseeing. Many reviews mention how unique it is to soak in a natural dome—a rare opportunity that’s both calming and quirky.

Once you arrive at the crater, you’ll find small changing rooms—note that towels and swimsuits are not supplied, so you might want to bring your own or rent them beforehand. The water is crystal clear and consistently warm, making it easy to unwind and enjoy the serenity. One reviewer described it as a “very cool experience soaking in a one-of-a-kind domed hot spring” with an owner who is “very accommodating and offers a relaxing experience.”

After your soak, the tour continues with stops at scenic and tasty spots. The Swiss Village Zermatt Resort is especially appreciated by visitors who indulge in chocolates, cakes, and drinks—perfect after a warm soak. If the weather’s right, you may also visit the Artesian Cheese and Dairy Farm, where you can observe cheese-making and sample fresh products. These stops add a wholesome, local touch to the experience.

Transportation and Group Size

The pickup points include your hotel or a central location like Wasatch Bagel, offering flexibility. The total duration is around 3 hours 15 minutes, which provides enough time to relax without feeling rushed, and allows for spontaneous stops or delays if needed.

The Cost and Value

At $125 per person, this tour offers quite good value considering everything included: private transport, entrance fees to attractions, and sampling opportunities. It’s a straightforward, all-in-one package that covers transportation, admission, and some tasty treats. But it’s worth noting that towels and swimwear are not included, so if you come unprepared, you might need to rent or buy these locally.

When you compare the cost to the experience—soaking in warm geothermal waters, learning about the local area, and sampling regional foods—it’s a fair price for an authentic, relaxing outing. Several visitors felt the experience exceeded expectations, especially given the friendly guides and the stunning views.
