With sulfur hot springs that feed mineral pools and bubble over travertine terraces near the banks of the Bighorn River, Hot Springs State Park in Thermopolis is by far Wyoming’s most-visited state park. There, patrons can brave water slides or splash around pools at two aquatic facilities, soak in a public bathhouse, amble along boardwalks or stay in one of two hotels. 

The Wyoming State Parks Department believes that with some TLC, the park can become an even bigger draw and economic engine. Hoping to polish it into a more modern, shiny destination, the agency is considering proposals that could significantly redevelop Hot Springs. 

“We want to make Thermopolis more of a year-round destination,” Nick Neylon, deputy director of Wyoming’s Outdoor Recreation Office and Division of State Parks, said at a recent meeting. “We think that with better facilities and more opportunities, that could happen.”

But the process could expel longtime concessionaires, including the owners of the historic Star Plunge, and contention has bubbled up over how the state is handling the park’s fate. 

“I think it would be a shame to allow an out-of-state investor to [run] the property,” Steve Voytilla, a former Thermopolis resident who has visited the Star Plunge since 1975, said. “I absolutely love coming to that 150-year-old facility. I don’t want a new facility there. It’s historic. It’s beautiful. It’s wonderful. It’s probably the coolest swimming pool in the world.”

The process has ignited questions about what Wyoming can gain, or lose, as it attempts to embrace an outdoor recreation and tourism economy while retaining long-held values of locals and visitors.

Landlord to mineral waters

The park is fed by a system of hot springs that originate deep in the earth and emerge near the river, primarily the Big Horn Spring. 

Native Americans visited the waters, which they prized for their healing qualities, long before white settlers, and the original 1-square-mile park land was established through a treaty between the Shoshone and Arapaho tribes and U.S. government. The land was later ceded to the state on the stipulation that there always be free public access to the therapeutic waters. What began as a reserve became the state park in 1929.  

Star Plunge was established as a wooden structure sometime between the 1890s and early 1900s, according to state documents; its outdoor pool was built in 1950. Nearby Tepee Pools was built in 1967 and rebuilt after a 1975 fire.

Unlike other parks in the state system, Hot Springs — which has grown to 1,100 acres — is a far cry from a wilderness experience. The springs are developed into indoor pools with steam rooms and slides, while parking lots and paved roads encircle the grounds. Playgrounds, picnic areas and two hotels sit in the park. 

Native Americans used Hot Springs State Park land for thousands of years. The Shoshone called it “Bah Guewa-na” (Smoking Waters). (Hot Springs State Park)

Its visitation numbers, at more than 1.5 million annually, far outpace other parks — none of which even hit 750,000. 

Concessionaires offer services at privately owned facilities: the Star Plunge and Tepee aquatic centers and Plaza Best Western and Days Inn Hot Springs hotels.

In recent years, some concessionaires have operated on short-term management agreements rather than long-term leases, Neylon said. Along with the fact that Wyoming prefers the longer arrangements, a 2019 law stipulates State Parks can no longer operate under year-to-year leases with concessionaires, “that we had to enter into longer-term agreements.” 

That, combined with a 2016 Hot Springs Master Plan that envisions the park “as a premiere [sic] destination, offering a diverse range of recreational opportunities in an unparalleled natural and cultural setting,” led to the recent developments. 

“The vast majority of people in the community that we hear from say that they want Hot Springs State Park to be … the jewel in our system,” Neylon said. “And to do that we need to have the best possible facilities. Unfortunately, the ravages of time have taken their toll on both the Hot Springs Hotel and the Star Plunge, and they are no longer everything that they could be.”

All four of the facilities were built decades ago and are in various stages of senescence.

Tepee Pools has a new owner; Hot Springs I Limited Partnership acquired it in November, with improvement and renovation plans. It and the Plaza Best Western Hotel are now both under long-term leases. Because Star Plunge and Days Inn Hot Springs have been operated under short-term management agreements, with the prior expiring at the end of 2024, Neylon said, Wyoming put out a request for proposals in November for constructing, operating and maintaining new or improved lodging and aquatic facilities within the park. “Our goal was to either have a new or a dramatically improved hotel facility and waterpark-type facility,” he said.  

The Wyoming State Parks and Cultural Resources Commission held a special online meeting last week to review the three bidders’ proposals. 

Wellness spa and more slides?

An evaluation committee scored the proposals, but bidders were kept anonymous at the meeting. In summary: 

  • Proposal A includes renovations to the hotel, such as a redesigned lobby and restaurant, a new mineral pool and glamping teepees along the riverfront. 
  • Proposal B includes transforming Tepee into a spa and wellness center in a full reconstruction while enhancing family facilities and the mid-century character of the Star Plunge with new slides, pools and a poolside diner; rebuilding or renovating the hotel to take advantage of the river area with upgraded dining and large riverfront sitting areas. Potential other offerings include nature trails, a drive-in theater, glamping facilities and a brew pub. 
  • Proposal C includes renovations and upgrades at Star Plunge with new features such as a splash park, pizzeria, ice cream parlor as well as replacing the vapor cave. It does not include any hotel or banquet facilities. 

The evaluation committee gave Proposal B the highest score, with 5,213 out of 6,000. Proposal C scored 3,379 and A scored 2,786. 

The parks commission approved the evaluation committee’s recommendation of Proposal B — which isn’t Star Plunge’s proposal. That recommendation now sits with State Parks and Cultural Resources Director Dave Glenn, who will make the final decision on who wins the bid. 

There is no protest process for the decision, Neylon said. 

Outcry 

Several members of the public — including residents of Montana, Colorado and Utah — attended the meeting to defend the Star Plunge and question the state’s interest in awarding the contract to someone other than long-time operator Roland Luehne, whose parents bought it in 1975. 

Luehne has been vocal about his desire to remain at the helm. In 2016 he started a change.org petition to “Save Star Plunge.” It has gathered nearly 12,000 signatures.

Many questioned the state’s right to expel Luehne, asked if it will compensate him and warned of litigation. Others defended Luehne for work he’s put into the facility. Some said they enjoy how affordable it is and worry a new operator — particularly one from out of state — would result in costlier, out-of-touch facilities.

“Be very careful of taking away a unique and precious gift that benefits us all,” said Thermopolis resident Danita Sayers. 

“I don’t understand why you would not try to work a deal with Mr. Luehne,” the former Thermopolis resident Voytilla said. “He’s brought a lot of money into the community.”

The notion that the state hasn’t tried to negotiate with Luehne, Neylon said, “couldn’t be farther from the case.” 

“We spent the better part of the decade trying to negotiate a long-term lease with both the Hot Springs Hotel and the Star Plunge,” he said. 

Luehne told WyoFile he didn’t sign a lease “because the state demanded that after 20 years, I would give them my facility and all the improvements with zero compensation … Who would sign that?” 

The long-term lease that began when Luehne’s parents bought the facility expired in 2008.

A forgone conclusion? 

The 2016 Hot Springs Master Plan laid the foundations for major changes in the park. 

“Over the years, the Hot Springs State Park’s legacy as a premiere [sic] health, wellness and outdoor destination has diminished,” the executive summary reads. “Today, some concessionaire operated facilities are deteriorated with extensive need for improvement and redevelopment … Facilities are not keeping pace with contemporary outdoor activities, recreational trends, and changing demographics.”

The plan also notes that the Big Horn Spring flows are diminishing, requiring a reassessment of resource management.  

The plan set forth a vision for a park redesigned to be more cohesive, diverse, pedestrian friendly and inclusive of natural features. It estimated costs associated with state park infrastructure improvements at $26 million, a number that doesn’t include concessionaire-borne expenses.

Luehne believes Wyoming has been attempting to push him out for years.  

“They’ve determined that they do not want a local small-business owner in Hot Springs State Park,” he said. By focusing on hotel improvements, he said, the request for proposals essentially rules him out by requiring the bidder to have deep pockets. 

Luehne’s family has poured a large amount of money into the facility, he said, and it generates more than 100,000 swims a year. The potential loss is “just heartbreaking.”  

Wyoming has followed its concessionaire guidance and protocols, said Brooks Jordan, Big Horn District manager for State Parks, and the RFP is a well-thought-out document based on need. A recent hotel study called for more lodging inventory, for example. 

He refutes accusations that Wyoming is operating in bad faith. 

“With the RFP, we’re really trying to do what’s best for the park, and the community and the state,” Jordan said. “We really want a world-class facility in Thermopolis.”

  1. I grew up in Thermopolis and Roland has been a staple for the community. He’s gone above and beyond for the park and town. My family loves how calm and natural the park is. Bringing in all the other hotels and amenities will ruin what the native Americans set out to do with the hot springs. A place for healing and peace.

  2. I remember when the Luehne family first moved to Thermopolis. The family worked together to create the LEGACY the STAR PLUNGE is today. It took awhile for the to see that these new people were down to earth good neighbors. They brought 5 children with them. Each & everyone of them put in thier time help build what was a ran down place. They made friends in the community, they helped support the community by starting other businesses, employing old & young alike recycling money throughout the community. Helping out the hands that feed them….giving back. I moved away, I went back to visit 25 years later. I went into the Star Plunge, low & behold Mr. & Mrs.Luehne recognized me & called me by name.We talked like if I had never left,a couple of the kids also talked but got right back to work at thier shift. The 1974 BB team was inducted to the hall of fame this past year. Roland came walking up recognized me Reminisced of times of when they first moved to Thermopolis. This is one of what makes this family down to earth. No corporations has this kind of relationship with people, to them your just a number & what I mean by that is $$$. Roland & family I hope & pray that they may see what you all bring to the table …..
    True friendship & caring for the people you have meet on your journey of operating a family run business. Good Luck my
    FRIEND.

  3. Some streamlining may help but the danger is that big plans that change the face of Thermopolis may end up excluding many individuals, due to cost increases. The intent of the Tribes, with the sale, in 1890 was community access to the healing waters, this may change with redevelopment.

  4. I liked that the park has a free 20 minute swim pool for people that are just traveling and don’t want to spend too much money, my wife and I went shopping in town and driving around, walked the board with our two doggies and went out to eat, having an out of town entity running the site will probably make everything more expensive and out of reach for ordinary citizens.

    1. Why is it big corporations have to come to wyoming ,and ruin everything.I feel bad for the people ofThermopolis. It already is a year round park.we have gone swimming there in the winter months.I say leave it alone!!!

  5. Just wondering if the state bothered to ask the Shoshone tribe and/or the descendants of Chief Washakie for input on any of these plans? After all, if it was a gift from Washakie.

    1. I have been enjoying the Star Plunge for the past eighty years and would hate to see it go. I worked there back in the 50’s. They are grandfathered in (in my opinion).
      Chief Washakie said that there should be free access to the waters for all the people

  6. A familiar story. Time to move on with those with deep pockets and a real business plan–if this is to remain the “crown jewel” in the State park system.

  7. My great grandparents, my grandparents, my parents, my wife and I, and my kids have always gone to the star plunge to swim and the old holiday in to sleep, and eat at the Safari club. And the best part is it’s always been the same for the most part. It all works and everyone is always happy. We don’t need anyone to come fix what’s not broke we like how it is and we’d like it to stay the same way it’s been, thank you very much! Money isn’t everything I understand it greases the wheels but the wheels of the hot springs seem to be doing just fine. Take your extra money and fix a road or maybe a bridge or two

  8. I agree with Jurosek. If you wanna take your family better do it now cause they are sure to triple the prices when the “world class facility” becomes a reality. They will price the average family out going. How disappointing to lose yet another fun thing to do to the money hungry. I don’t object to fixing up and modernizing; I just object to the ridiculous amounts of money they will charge.

  9. I found it disturbing how the committee would not even take Public Comments during the last online forum. Clearly, the individual members have decided to force out two local business owners, whom have successfully operated for years to provide for the Public what was guaranteed in a Federal treaty over 100 years ago, to sell out to an Our of State entity. This ‘Disneyland’ proposal under the auspice of Progress’ is both unrealistic and reeks of corruption. It is greed, plain and simple.

    I agree, there are need for improvements in any capacity, but why did the State not even try to work with the local business owners instead of force them into a large ‘sell off?’ What do the local representatives for Hot Springs County say in the State Legislature? Especially, since local business has been affected.

    The new owner of the Tepee Pools charges $50 for two hours at his other exclusive properties…. I feel that this move by the State Parks was not in the best interest of the majority of the local population.

    I speak with more Coloradans’ who are more and more visiting and relocating to the State of Wyoming to escape the so called Progress’ in their State. I am not against growth… I am for responsible growth. The issue in Thermopolis is a concern.

  10. I Denise S. From ND have been coming to Thermopolis, Wyoming since I was 25yrs. Old. My parents introduced me to this hotsprings. It is by far The STAR PLUNGE and TEEPEE Hotsprings the best their is in the USA!!! I have been to many of them and this is my favorite!! A clean, cozy and very soothing and relaxing atmosphere! Please leave these hotsprings naturally in the state park. Changes don’t always bring better things. It is all about family and they have done an awesome job maintaining the facility and even recognize you by face. That always means alot. The state pool in the middle adds alot also. Something different and unique.

  11. If there’s 1.5 million customers s day in the park then that’s roughly 4,109 visitors a day , and you show 2 people in the pool , that’s either inflating the visitor count or false advertising of how the pools really look

  12. I’m a huge fan of Thermopolis and the State Park and am pleased to read this positive news about much-needed upgrades and modernization of these dated facilities. Thermopolis is a jewel from the natural landscape, the bison and hot water features. The fishing is bringing people from around the state and out of state. New bike trails have been built.There is a lot of positive investment happening in downtown Thermopolis- restaurants, bakeries, bookstore etc. The county government is supporting new uses to build out their recreation and hospitality industries. It is good to see the State stepping up to make these investments.

  13. Personally, I just want clean, affordable places to enjoy the springs. The last time I went to the Star Plunge I was very satisfied with the obvious improvements. HSSP does not really need more bells and whistles, just consistent maintenance, in my opinion.

  14. The state of Wyoming is greedy. And the idea that we need a shiny expensive “world class facility” is based on greed, not what’s good for Wyoming people. You think the pools are expensive now? Wait until we get their cherished “world class facility”. Ordinary people will not be able to afford to go there. It will be for the rich and famous. Wyoming needs hot springs that are slow paced, quiet, friendly, family oriented and with some history behind them like the Teepee and Star Plunge are now, not some cash oriented, shiny spectacle. What I have heard is that the new “world class facility” will use ordinary non-mineral water. What is the use of that? We have hot mineral water there in the park. Why not continue to use that water. It’s healing and good for everyone that goes there. If its starting to run low we can make adjustments but to build shiny expensive facilities that use plain water doesn’t make sense at all. The state has been jerking Roland around for years over his lease and his management of the Star Plunge. They have kept their thumb on him hoping that he would want to get out but he has endured and he doesn’t want to get out. The state of Wyoming’s ideas for the park are based on money, greed, power, and control. We don’t need their shiny spectacle. We need what we have now. A quiet simple place to take the family and where Wyoming people and out of staters alike can come and relax and heal the body and the mind. And that is affordable. People have been taking their families to the Star Plunge and Tepee for decades. Its a place that holds many memories for families. We are all going to have to reach deep into our pockets to make up for that $26 million plus that the state will spend. Leave it alone. Its working. Make improvements and try supporting the pools that we have now for once. Get the dollar signs out of your eyes. We don’t need a shiny spectacle in Thermopolis.

  15. Star plunge isn’t dirty. Very very clean. Many improvements by the owner. The staff very professional. Polite. Life guArds do their job and make all safe. Leave Star Plunge the way it’s being run. Look at the money they bring to Thermopolis. Outside is always clean also. Outsiders and parks department. Are gravely making a huge mistake to want to change a historical place. I went there as a child. I’m 71 years old

  16. I can see that some of the facilities are in need of improvement but bringing in outside management would, in my opinion, ruin the ambiance of the facility in regard to a “family oriented” resort. The charm of this old facility it precious. High powered hotels are not necessary. If too many “amenities” are included the price will be raised and many people will fore go coming into the park. It is such a great natural entertainment facility for all ages and it would be a shame if it is commercialized beyond it’s current charm! Please be careful when considering the future of the Hot Springs area!

  17. I live in Colorado,
    To me it sounds like BIG BUSSINESS moving in,squeezing out Yor local,home- grown people to surrender a local treasure, in the pursuit of CAPITALISTIC GREED.BIGGER is not always better! I have witnessed the prostitution of Too many gems.Keep Thermopolis local and original. Don’t be a bunch of wholesale! This article has persuaded me that I need to return this Summer to an Old Friend, instead of visiting an unrecognizable POS later.KEEP THERMOPOLIS ORIGINAL!!

  18. There’s quite a lot missing from the options under consideration. Number one is the loss of many acres of the original 640 acres to development for the county fair grounds, weed and pest, county road and bridge, high school and grade school, senior center, library, retirement home, children’s home, railroad right-of-way, and state highway right-of-way. The park needs to be expanded to the east by acquiring an additional section of land from the Wyoming Dinosaur Center owner via a simple land trade – a no cost expansion – which would greatly expand the buffalo pasture and facilitate trail connection to a large block of BLM land to the east of the park. Most people do not realize just how much of the original 640 acres has been whittled away by other uses – its a lot. There’s only so much development that can be squeezed into the remaining acreage and its being stressed by the rapidly growing float industry which utilizes the existing boat ramp. The proposals apparently don’t address the needs off the float industry – we now have 6-8 fulltime river guides and the usage is growing – and the float industry goes right through the middle of the park – has it been adequately considered?? And, the public love the buffalo – why hasn’t expansion of the small herd not been included??? Finally, the importance of wildlife and natural ecosystems has been long ignored in favor of more development at the expense of wildlife – shouldn’t our state parks reflect more on the true wild Wyoming rather than on a mini theme park. I can tell you from personal experience that wildlife are not exactly welcome at the park – the staff just doesn’t want to deal with them – especially deer and geese. And, the park routinely sprays the grass areas with weed killer even in the play grounds and close to the river. How about staying natural and limit the development.

    1. Please add the Hot Springs Hotel and the Best Western Hotel to the list of users of the park’s acreage.
      The Hot Springs County fairgrounds is located on park acreage and is supported by a mill levy on property tax – it brings in an incredible number of western related events such as rodeo, roping, cutting, horse clinics, demo derby, etc. Therefore that section of the park is being widely utilized by the public for recreation and its upkeep and maintenance is paid for by the Hot Springs County property tax payers.

    2. The People of Thermopolis do not want change or want a state of the art water park, We live here because of the hot springs. Leave it alone and leave it the way it’s been forever.. Last thing we need is a big fancy water park.. Thermopolis is a amazing place just the way it is…

  19. I say tear it down. Other than a new coat of paint, it’s the Same place as it was in 1994 when I was going there as a kid – same slides, same diving board. Dirty. Overpriced – like pushing 100 bucks for a family overpriced. And boring. At least when I was a kid there was an arcade.

  20. Edward Abbey warned us about what would happen when developers got a hold on our special places.

    1. Yep. Once the money-eyed swamp rats get their greedy paws on places like Hot Springs County, Wyoming, the entire state is destined to take the Blue Thunder Run straight to hell.
