Dubois has no shortage of extraordinary experiences, but even this small mountain town has its secrets.\u00a0<\/p>\n

For anyone seeking a secluded spot in the area, ask a local business owner\u00a0and they\u2019ll tell you how to reach Warm Spring Geyser.<\/p>\n

Even in a state with more geysers, hot springs, and thermal features than any land mass in the world, Warm Spring Geyser stands out. It\u2019s a pristine pool of thermal water at the bottom of an open cavern and accessible to anyone intrepid enough to find and descend into it.<\/p>\n

\u201cIt is a semi-secret destination that’s not unique to Wyoming, but unique in Wyoming,\u201d said Casper resident Tobias Fousek. \u201cIt looks like something you find down in the Caribbean.\u201d<\/p>\n

Warm Spring Geyser sits on a parcel of Bureau of Land Management land near Dubois at an elevation of 7,260 feet.<\/p>\n

While it has geyser in the name, it behaves more like a placid hot spring. The water isn\u2019t even all that hot.<\/p>\n

\u201cIt\u2019s only around 80 degrees,\u201d Fousek said. \u201cIt\u2019d be like a warm soak, not a hot spring, if you got into it.\u201d<\/p>\n

According to the website Soaking Springs<\/a>, Warm Spring Geyser has an average temperature of 84 degrees, \u201clike warm bath water.\u201d The thermal water is rich in dissolved calcium and magnesium and has a neutral pH of 6.8.<\/p>\n

Because of the high concentrations of dissolved minerals, the water has been described as \u201cvery buoyant\u201d for anyone who decides to wade in.<\/p>\n

Fousek has seen the thermal water but never stepped into it. He estimated the pool is more than 10 feet at its deepest point.<\/p>\n

\u201cI\u2019d guess that it\u2019s deeper than I am tall, so maybe 10 feet over by the vent, but that’s just guesstimating,\u201d he said.<\/p>\n

What makes Warm Spring Geyser unique is how it\u2019s situated in the landscape. The only way to reach the water is through a steep, narrow crevice that opens into the water-filled cavern.<\/p>\n

The average person would find the descent difficult and dangerous without assistance. A\u00a0climbing rope was installed to help people get down and back up.<\/p>\n

Once inside, Warm Spring Geyser is a surreal experience. The blue water reflects on the walls and ceiling of the cavern, covering them with a hypnotizing pattern.<\/p>\n

\u201cIt is definitely worth the adventure, just to get out there and explore,\u201d Fousek said.<\/p>\n

Many people can tell a visitor how to get to Warm Spring Geyser. Fousek is among them, which is why he\u2019s never shared it publicly.<\/p>\n

\u201cIt\u2019s definitely a secret, and that\u2019s what\u2019s fun about it,\u201d he said. \u201cIf you are persistent or good at finding stuff online, it’s definitely out there, but finding it is part of the fun.\u201d<\/p>\n

The most reliable way to find Warm Spring Geyser is to ask business owners in Dubois. Someone at the Jackalope Caf\u00e9 will know how to get there, although they might suggest taking the more direct route that cuts through private property.<\/p>\n

Fousek said it\u2019s entirely possible to reach the spot via public roads, even if it takes a bit longer. Some\u00a0might even try using Google Maps, but that isn\u2019t entirely reliable either.<\/p>\n

\u201cIt’s listed on most maps and digital mapping technology, but it’s listed multiple times,\u201d he said. \u201cYou have to figure out which one is right.\u201d<\/p>\n

But can you swim in Warm Spring Geyser? Nothing\u2019s stopping anyone from wading into the water, but “can” and “should” are different concepts.<\/p>\n

Soaking Springs doesn\u2019t consider it a soaking spring. They have a warning that Warm Spring Geyser \u201cisn\u2019t a traditional hot spring,\u201d given the \u201cgeyser\u201d in its name, and common hazards could include boiling water, toxic gases, and unstable ground.<\/p>\n

Fousek isn\u2019t sure about any of those hazards, but he\u2019s personally opposed to anyone swimming in the warm spring. There\u2019s a whole other world that bears consideration.<\/p>\n

\u201cI know that it\u2019s monitored by several agencies,\u201d he said. \u201cIt\u2019s a very fragile ecosystem. Yes, people swim in it all the time, but I definitely don’t recommend anyone actually swim in it.\u201d<\/p>\n

If preserving the environment’s integrity isn\u2019t enough, Fousek pointed out the obvious hazards that should discourage reckless behavior. Someone could slip and fall down the opening, and being injured at the bottom of a cavern in a remote area is always hazardous.<\/p>\n

\u201cAnytime you’re outdoors, or around water like that, there could be all kinds of nasty surprises,\u201d he said. \u201cI\u2019ve never gone in, and I don\u2019t think I ever would.\u201d<\/p>\n

Warm Spring Geyser might not be that hard to find, but getting there is half the fun \u2013 and the challenge.<\/p>\n

Fousek couldn\u2019t see anyone getting to the cavern’s opening without a high-clearance 4×4 vehicle. Anyone in the Dubois area who knows where it is would probably suggest the same.<\/p>\n

\u201cYou\u2019ll know it when you find it, but it can be dangerous,\u201d he said. \u201cYou have to climb a bit to get down there. You can get great pictures from above, but anyone with mobility issues would struggle to get close to it.\u201d<\/p>\n

It\u2019s possible to enter the cavern without entering the water, but Fousek has always felt better enjoying Warm Spring Geyser from a distance.<\/p>\n

\u201cYou can get some beautiful pictures from above,\u201d he said. \u201cA lot of people think of it like Thermopolis or Yellowstone, but I really urge people to be careful. There\u2019s a whole ecosystem down there.\u201d<\/p>\n

If you\u2019re in the area, there\u2019s more to see around Warm Spring Geyser. An old logging road nearby will lead curious explorers to a historic wooden flume built on a mountainside, still standing after decades of neglect.<\/p>\n

It\u2019s also a great spot to take in the landscape of the Wind River Range. You can even see Dubois from there, although that might be saying too much.<\/p>\n

Fousek encouraged anyone interested in Warm Spring Geyser to go find it, but do so responsibly.<\/p>\n

\u201cLike anything in nature, be respectful,\u201d he said. \u201cClean up after yourself, don’t leave any trace, and don\u2019t damage anything. We’re all out here exploring this world together.\u201d<\/p>\n

Another reason many people don\u2019t share much about Warm Spring Geyser publicly is the flood of misinformation about it. Fousek finds much of what he\u2019s heard amusing, as it adds to the thrill of going out and finding it.<\/p>\n

While he is happy to correct any misinformation, there\u2019s one \u201cfun rumor\u201d he can\u2019t help but mention: the toxic slugs.<\/p>\n

\u201cWhen I first started looking for it, my coworkers told me that I definitely couldn’t swim in the water because of toxic slugs,\u201d he said. \u201cI\u2019ve never seen a slug there, but whenever I tell people about it, I always joke and tell them that there are toxic slugs. It\u2019s just a rumor.\u201d<\/p>\n

Intrepid visitors might not find any toxic slugs, but they will find a memorable experience. Fousek suggested making the most of the adventure by visiting Dubois.<\/p>\n

“There are a lot of other beautiful areas to explore near Warm Spring Geyser, and Dubois is full of very friendly people,\u201d he said. \u201cThere are other places up there that are even more secret, so I really urge exploration. This one\u2019s gotten out, so make a day of it.\u201d<\/p>\n
