Getting There & Parking
Understanding how to get to Thermopolis is the first step in planning your trip. Given its relatively remote location in central Wyoming, driving is the most common and often most convenient method of arrival. Thermopolis is situated at the intersection of US Highways 20 and 120, making it accessible from various directions. From the north, you can reach Thermopolis via US-20 from Cody or Worland. From the south, US-20 connects it to Casper, while US-120 provides a route from Shoshoni and Riverton.
If you're flying in, the nearest major airport is Casper/Natrona County International Airport (CPR), approximately 100 miles southeast of Thermopolis. Driving from CPR to Thermopolis typically takes about 1 hour and 45 minutes. Another option is Yellowstone Regional Airport (YRA) in Cody, about 90 miles northwest, which is roughly a 1 hour and 30 minute drive. Rental cars are available at both airports, and we highly recommend securing one for the flexibility to explore the area at your own pace. For those coming from further afield, Denver International Airport (DIA) is a larger hub, but it's a considerable drive of about 5 hours and 30 minutes to Thermopolis.
Once you arrive in town, Thermopolis parking is generally straightforward and plentiful. Hot Springs State Park, the town's central attraction, offers ample free parking throughout its grounds, including designated areas near the Bath House, Star Plunge, and Hellie's Teepee Pools. Parking at the Wyoming Dinosaur Center is also free and readily available directly at the museum. Most hotels and motels in Thermopolis provide complimentary parking for their guests. We’ve found that even during peak season, finding a parking spot is rarely an issue, allowing you to focus on enjoying your visit rather than worrying about vehicle logistics.
Top Things to Do
When it comes to things to do at Thermopolis, the town truly offers a diverse array of attractions that cater to all interests. Our team has explored every corner to bring you the definitive list of experiences.
Hot Springs State Park
No visit to Thermopolis is complete without experiencing the therapeutic waters of Hot Springs State Park. This is where you'll find the world's largest mineral hot spring, and remarkably, the State Bath House offers free public bathing in a 104-degree pool for 20-minute intervals. The State Bath House is typically open daily from 8 AM to 5:30 PM, though it's closed on Thanksgiving, Christmas, and New Year's Day. Beyond the public bath, you can also enjoy the larger, family-friendly commercial pools: Star Plunge and Hellie's Teepee Pools. Star Plunge offers indoor and outdoor pools, slides, and a vapor cave, with daily operating hours generally from 9 AM to 9 PM, and admission costing around $15-20 for adults. Hellie's Teepee Pools also features multiple pools, a hot tub, and a steam room, with similar hours and pricing. We recommend checking their respective websites for the most current 2026 hours and pricing, as these can be subject to change. Stroll across the Suspension Bridge for scenic views of the Bighorn River and the colorful mineral terraces formed by the spring outflow.
Wyoming Dinosaur Center
For a journey back in time, the Wyoming Dinosaur Center is a must-visit among the things to do in Hot Springs County. This world-class museum boasts an impressive collection of dinosaur skeletons, including a rare Archaeopteryx, and over 30 mounted skeletons. It's one of the few places in the world where you can see a real Archaeopteryx fossil, making it a truly special experience. Beyond the exhibits, the center offers a unique "Dig for a Day" program, allowing visitors to participate in actual paleontological digs during the summer months – a truly unforgettable hands-on experience (reservations are highly recommended for this program). The museum is typically open daily from 8 AM to 6 PM during the summer season (May-September), with reduced hours in the off-season. Admission is approximately $12-15 for adults.
Wyoming Whiskey
Just a short drive from downtown, the Wyoming Whiskey distillery offers tours and tastings for those interested in the craft of bourbon making. Learn about their grain-to-glass process and sample their award-winning spirits. Tours are usually available by reservation, and our team suggests checking their website for current 2026 tour schedules and tasting room hours, as these can vary seasonally.
Other Attractions & Activities
- Thermopolis Museum & Cultural Center: Explore local history, pioneer artifacts, and exhibits on the area's Native American heritage.
- Legend Rock Petroglyph Site: Located west of Thermopolis, this site features over 300 petroglyphs, some dating back 10,000 years. It’s a remarkable outdoor gallery of ancient art.
- Bighorn River Fishing: The Bighorn River, flowing through Thermopolis, is renowned for its excellent trout fishing. Many local outfitters offer guided trips.

From soaking in mineral springs to unearthing ancient history, the things to do at Thermopolis provide a rich tapestry of experiences for every visitor.
Best Time to Visit
Determining the best time to visit Thermopolis largely depends on your priorities, but our team generally recommends late spring through early fall for the most pleasant experience. From May to September, the weather is typically warm and sunny, ideal for enjoying outdoor activities like hiking, exploring Hot Springs State Park, and participating in the Wyoming Dinosaur Center's "Dig for a Day" program. Average high temperatures during these months range from the low 70s to upper 80s Fahrenheit, with comfortable evenings.
Summer (June-August) is peak season, offering the warmest weather and all attractions operating at full capacity. However, it also means more visitors, especially at the hot springs. If you prefer fewer crowds and slightly cooler temperatures, late spring (May) or early fall (September-October) are excellent alternatives. The fall foliage along the Bighorn River and in the surrounding areas can be particularly beautiful. Winter (November-April) brings colder temperatures and snow, but the hot springs remain a cozy and inviting escape, often less crowded. Just be prepared for winter driving conditions. We find that the shoulder seasons offer a perfect balance of good weather and fewer people, making them an ideal time to experience Thermopolis.
Where to Stay Nearby
When planning your trip, finding comfortable Thermopolis lodging is key to a relaxing experience. The town offers a variety of accommodations, from well-known hotel chains to charming local motels and RV parks, ensuring there’s something to suit every budget and preference. Most options are conveniently located within a short drive of Hot Springs State Park and other major attractions.
For those seeking traditional hotel stays, you'll find familiar brands offering standard amenities. Many local motels also provide clean, comfortable, and often more characterful options, frequently with competitive pricing. If you're traveling with an RV or prefer camping, Thermopolis has several well-equipped RV parks and campgrounds, some even offering direct access to the Bighorn River or views of the surrounding landscape. These can be an excellent choice for families or those looking for a more immersive outdoor experience.
While Thermopolis itself is the primary hub for accommodations, the surrounding Hot Springs County area doesn't offer extensive alternatives if you're looking to stay outside of town. Therefore, focusing your search for where to stay near Thermopolis squarely on the town itself is your best bet. We recommend booking your lodging in advance, especially if you plan to visit during the peak summer months, to ensure you secure your preferred option. Many establishments offer amenities like indoor pools (beyond the hot springs), complimentary breakfast, and pet-friendly policies, so be sure to check what each offers to match your travel needs.
