If you’re eyeing something a little different for your Utah adventure, the Natural Indoor Hot Spring and Spa Utah Crater tour might just be worth considering. While we haven’t personally taken this exact trip, reviews and detailed descriptions paint a pretty intriguing picture of what it offers. Think of it as an opportunity to unwind in North America’s only year-round indoor geothermal hot spring, combined with a bit of sightseeing and tasty stops along the way.
What we really appreciate about this experience is how it combines relaxation with local charm. First, the hot spring itself is described as a truly one-of-a-kind spot—an indoor dome where the water hovers around a consistent 94°F (about 90°F in the water source itself). This means you can enjoy a soothing soak anytime, regardless of the weather outside. Second, the tour includes some unexpected but delightful stops, like visiting a Swiss Village bakery or an artisanal cheese farm, adding a taste of local flavor and fun to the experience.
A possible snag? The tour’s flexible schedule (anywhere between 8 a.m. and 6 p.m.) can be a bit of a puzzle when planning, especially if you’re on a tight timeline. Plus, keep in mind that towels and personal swimwear aren’t included, so you’ll need to bring or rent those separately. This tour is perfect for travelers who want a relaxing, laid-back day with some scenic sightseeing and don’t mind organizing their own swim gear.
This experience suits those looking for a relaxing day with a touch of local flavor—great for couples, friends, or even solo travelers who want to unwind in a natural, unique setting while exploring a bit of Utah’s charming surroundings.

The Indoor Hot Spring in Detail
The highlight of this experience is undoubtedly the Utah Crater’s indoor geothermal spring. The dome structure provides a cozy, private atmosphere to soak while marveling at the natural formation. The water is described as very warm, at about 94°F, which is perfect for a leisurely swim or just lounging in the warm waters. One reviewer praised it as a “very cool experience soaking in a one-of-a-kind domed hot spring,” emphasizing its uniqueness.
Because it’s not volcanic but a geothermal spring formed over thousands of years, the water’s origin is quite different from volcanic hot springs elsewhere. The source is about two miles underground, which adds a bit of geological interest, especially if you’re into nature’s underground mysteries.
The Stops That Add Charm
Beyond the hot spring, the tour includes some delightful stops. The Swiss Village Zermatt Resort is a favorite, especially for those with a sweet tooth or a fondness for Swiss treats. Visitors often enjoy sampling chocolates, cakes, and drinks after their soak, making it more than just a quick visit. However, note that tours starting after 2 p.m. might not include this stop because the resort closes later in the day.
Alternatively, there’s the Midway Chocolate Factory, which is equally appealing and offers a chance to see how homemade chocolates are crafted. If weather and time cooperate, an additional visit to the Artesian Cheese and Dairy Farm is possible, where sampling cheese and observing production adds another authentic local flavor.
The Logistics and Practicalities
Transportation is private, making the experience feel more personalized and comfortable. The tour includes bottled water, entry to the hot spring, and access to the other attractions. It’s important to bring your own towels and swimwear, or plan to rent or buy them on-site, as these aren’t provided.
Tour times are flexible—scheduled anytime between 8 a.m. and 6 p.m.—which is great if you prefer to customize your day. Just remember, since this is a non-refundable tour, cancellations are not possible, so planning ahead is key.
Highlights from Reviews
One of the top compliments comes from Deborah, who called the experience “very cool,” praising the “family who owns and runs it” for their accommodating, relaxing vibe. Several reviewers appreciated the knowledgeable guides, with one saying, “Dave was a very good tour guide,” and another mentioning that their guide, Mike, “exceeded expectations” with local insights.
The hot spring itself gets glowing reviews, with one traveler describing it as “amazing,” and families sharing how their kids enjoyed the experience as well. Of course, some mention that the tour operator’s overall service could be more attentive, but that doesn’t seem to tarnish the main appeal—the spring itself.
The Value for the Price

At $125 per person, the tour offers a well-rounded experience. You’re getting transportation, entry fees, and delightful stops, which can easily add up if you try to do these independently. However, keep in mind that the actual soak is 45 minutes, which is enough for most people to unwind but not a full day of lounging.
Most reviewers felt that the experience was worth the cost, especially those who appreciated the personal touches from their guides and the chance to combine relaxation with sightseeing. If you’re someone who values a thoughtfully curated experience with local flavor, this tour is likely a good fit.
Who Would Love This Experience?
This tour is ideal for travelers who want a relaxing day in Utah’s unique geothermal waters without the hassle of organizing multiple stops themselves. It’s great for couples seeking a romantic, low-key outing, friends wanting to unwind together, or solo travelers who enjoy guided experiences. People interested in geology or local culture will also find the stops interesting, as they add context and flavor to the day.
