One pool sits around 103°F, another near 107°F, and the small, famously fierce “lobster pool” reaches roughly 117–118°F. At this free Wyoming soaking stop, choosing where to get in is not an afterthought. The water temperature shapes the visit.
The setup is refreshingly straightforward: public outdoor mineral pools, a nearby river, basic changing facilities and a mix of people passing through and local regulars. It is open 24 hours a day throughout the year, with no admission charge. A donation box gives bathers a simple way to help with cleaning and upkeep.
You can make it a short break on a long drive or spend a while rotating among hot water, cooler pools and the river edge. The place has the easygoing rhythm of a community gathering spot rather than a polished spa.
Start by picking your heat level
The three main pools offer a useful range rather than three versions of the same soak. The coolest of the group, at about 103°F, is still properly warm and gives people a comfortable place to settle in. The larger hot pool, around 107°F, raises the intensity without quite reaching the lobster-pot end of the spectrum.
Then there is the lobster pool, also called the lobster pot. At 117–118°F, it is for brief, careful encounters rather than a long leisurely float. Its name is blunt, memorable and probably all the warning most people need.
Posted pool temperatures near the shower area make it easier to choose before heading outside. On a visit with friends or family, that range also gives everyone an option; not everybody is looking for the same degree of heat.
Hot water meets the river
Beyond the maintained main pools, smaller rock-lined soaking tubs sit along the river. Here, hot spring runoff mixes with cooler moving water, producing a more natural and less uniform soak than the central pools.
The river tubs invite a little experimentation. A person can settle into a warmer pocket, shift toward the current for relief, or step between the hot pools and cooler river water. That back-and-forth is a pleasant way to extend a stop without spending the whole time in one temperature.
These are natural rock pools rather than fully developed spa basins, and conditions can vary. Algae is visible in portions of the natural pools and may make surfaces slippery, so getting in and moving around calls for a little care.
A practical place to change and rinse off
The facilities cover the basics: restrooms, changing areas, open showers and lockers are available on site. Visitors commonly use the showers and changing rooms, check the temperature posting, then head toward the pool that sounds right for the moment.
The lockers are not individually locked, so they are best treated as a place to hold clothing and simple belongings rather than a secure storage option for valuables. Bring a towel, too; this is a self-contained soaking stop, but not a full-service operation.
The pool area does not allow glass, and pets are not permitted inside it. Those small rules help keep a shared outdoor facility workable for the steady mix of bathers coming and going at all hours.
Open after dark and through winter
Round-the-clock access changes the character of the springs. A daytime visit can be a break in a road trip, while an evening soak offers a quieter stretch of open-air water after the day has cooled down.
The hot springs remain available year-round, including snowy weather. Steam above the pools and snow around the grounds make a strong case for cold-season soaking, though the setting remains simple and outdoorsy rather than resort-like.
There can be a noticeable sulfur note in the water, an ordinary feature of a mineral-spring setting. It is part of the deal here, along with the open air, the river nearby and the decidedly no-frills facilities.
A summer pool for a different kind of water day
In summer, a separate swimming pool adds another option for people traveling with children, looking to cool off or simply wanting a little more activity between soaks. It has pool toys, life jackets and a rope swing.
The seasonal swimming pool has been reported at $3 per person, separate from the free hot springs. The hot pools remain the year-round fixture; the swimming pool is the warm-weather extra.
A social stop with room for a quiet soak
The crowd tends to include both travelers and people who know the routine well. Conversations can strike up easily in the pools, and local bathers help give the place its familiar, public-gathering-spot character.
At the same time, a visit does not have to be social. Weekday and evening stops can be quieter, and the multiple soaking areas make it possible to drift away from the main pools for a more low-key stretch beside the river.
The grounds have a practical, primitive-camping sort of feel: functional, outdoors-focused and built around the water rather than extra polish. That suits a Wyoming road trip just fine. The best approach is simple—bring a towel, keep glass out of the pool area, choose a temperature that makes sense, and leave a donation if the soak has improved the day.
