Hotels for 18- to 20-year-olds in Thermopolis, Wyoming

Thermopolis may be small, but it’s got a big claim to fame: the world’s largest mineral hot springs. You can soak in the pools at Hot Springs State Park, wander through the park’s bison herd, or check out the local dinosaur museum for a quirky change of pace. The town has a relaxed, outdoorsy feel that makes it easy to unwind between adventures.

For under-21 travelers, though, options are almost nonexistent - there’s just a single hotel here that welcomes younger guests. If you’re planning a trip, it’s best to book early, or be prepared to look in nearby towns for more availability.

• 1 Paintbrush Inn Thermopolis $$$

  
  Paintbrush Inn
  Guest Rating 8.2

  Our opinion: Free parking, Wi-Fi, and complimentary bikes make this a convenient, budget-friendly stop in Thermopolis. Some rooms add practical extras like a microwave, coffee maker, fridge, and in some cases a kitchenette, which helps keep things simple and affordable on the road. Breakfast is not included, so plan to pick something up in town.
  
  The property has a simple motel-style setup rather than a trendy boutique feel, but it covers the basics well. Rooms include air conditioning, a flat-screen TV, and a private bathroom, and the option of a kitchenette adds flexibility for longer stays or cheap, easy meals. There’s also a barbecue area, which gives it a slightly more relaxed, outdoorsy feel. Overall, it’s more about function than design, but that can be a plus when you just want an easy, low-stress stop.
  
  It’s set in Thermopolis with straightforward access to the local area, including Hot Springs County-Thermopolis Municipal Airport nearby. The location works especially well if you’re passing through on a wider Wyoming trip or heading in the Yellowstone direction. Having shops and breakfast spots in town makes the lack of on-site dining less of a problem, and the area is also good for cycling if you want to make use of the free bikes. For a small-town stopover, it’s convenient without feeling too far out.
  
  Guest feedback is generally positive about the location and the staff, with several people specifically mentioning both as highlights. Travelers also appreciated the in-room conveniences like the microwave, coffee machine, and fridge, especially for short stays. Criticism is limited, but a few downsides do come up: there’s no breakfast, one guest found the shower small, and another mentioned the bed was hard. Even so, reviews suggest it does its job well as a simple, reliable place to stay. Read more

• 2 Hot Springs Hotel & Spa Thermopolis $$$

  
  Guest Rating 7.5

  Our opinion: Featuring its own outdoor mineral hot spring tub and a spot right inside Hot Springs State Park, this place has a big location advantage for a short Thermopolis stay. It works best for travelers who care more about soaking, walking to sights, and having free parking and breakfast than staying somewhere polished. The on-site restaurant and bar, 24-hour front desk, gym, Wi-Fi, and billiards room add convenience, and some ground-floor rooms have easy access outside. Just know this is not the pick for a stylish or super-modern stay, since many guests felt the property is overdue for updates.
  
  The overall vibe is old-school roadside hotel meets quirky safari lodge. Rooms are fairly basic, with cable TV, mini-fridges, and private bathrooms, while the standout features are the outdoor hot spring bath, hot tub, and the lodge-style bar and restaurant filled with taxidermy and travel memorabilia. Some guests found that atmosphere memorable and fun, while others thought it felt dated or too eccentric. There’s also a fitness center, business center, snack vending, and generally easy parking right by the building, which keeps things simple for a one- or two-night stop.
  
  The location is one of the strongest reasons to stay here. Set in Thermopolis near Hot Springs State Park, it puts you close to the town’s famous thermal pools, boardwalks, river views, and hiking options, and several reviewers liked being able to leave the car parked and explore on foot. East Thermopolis is nearby, the local airport is only a few minutes away, and the Wyoming Dinosaur Center is also an easy outing from here. For a base focused on the park and the town’s main attractions, it’s very convenient.
  
  Reviews are pretty mixed, but the same themes come up often. Guests regularly praised the location, friendly staff, on-site hot mineral tub, decent breakfast, quiet rooms, and the restaurant’s atmosphere, with a few specifically calling the steaks great. The biggest negatives were the hotel’s worn condition, older rooms, inconsistent cleanliness, maintenance problems like drains, TVs, showers, and AC units, plus occasional slow service at check-in or in the restaurant. In short: people tend to enjoy the setting and hot springs most, but the condition of the rooms can make the value feel hit-or-miss. Read more

• 3 Rainbow Motel Thermopolis $$$

  
  Guest Rating 6.8

  Our opinion: Close to Thermopolis’s hot springs, this older motel offers a practical, low-cost base with free parking, free Wi‑Fi, and an easy walkable setting. It suits a short stay best, especially when you mainly want a clean room after exploring, and some units are more spacious than expected with extra seating or kitchenette-style setups. Keep expectations realistic, though, since the property is dated rather than polished.
  
  The vibe is classic old-school roadside motel: simple, dated, and a little worn, but often described as clean and roomy. Rooms include air conditioning, a flat-screen TV, a desk, and a private bathroom with shower and basic toiletries, and several guests mentioned large layouts that felt bigger than expected. A few reviews even noted a cottage-like or retro character, which gives it more personality than a generic chain stop. The flip side is that the age shows - some furnishings, bathrooms, and cooling systems seem overdue for updates, and comfort can vary from room to room.
  
  Location is one of the strongest reasons to stay here. It’s in Thermopolis with easy access to Hot Springs State Park, downtown spots, and plenty of food options, so you can get around with minimal driving. Several guests said they could walk to major local attractions, restaurants, and shops, and the motel is also a handy base for hiking in the area. There’s even an ice cream and burger spot next door, which adds to the easy road-trip feel.
  
  Reviews are mixed but fairly consistent about the pros and cons. Guests regularly praised the friendly, helpful staff and the cleanliness of the rooms, especially considering the motel’s age. The biggest complaints were noise, smokers lingering outside rooms, outdated facilities, weak or awkward air conditioning, and maintenance issues like worn interiors or minor room problems. A few travelers also mentioned unreliable Wi‑Fi, tight parking, and occasional reservation mix-ups, so it’s smart to keep expectations realistic and double-check details before arrival. Read more
