Hot Springs Park in Thermopolis — Online Webcam
Thermopolis Hot Springs — a unique geothermal zone of Wyoming
Hot Springs Park in the town of Thermopolis is one of the most unusual places in the state of Wyoming. Here nature has created the world's largest mineral hot spring, which erupts from underground with impressive force. The Big Spring produces water at a constant temperature of 135 °F (57.2 °C) at a rate of about 2,200 gallons per minute. This makes it a true geological wonder, attracting tourists from across the region.
The water rises from great depths, where it is heated geothermally, and on its way to the surface dissolves numerous minerals from the surrounding rock. This is why it contains a rich mineral composition and has a characteristic sulfurous smell. On the Hot Springs Park webcam, you can observe how this water flows to the surface, forming a unique landscape around it.
Mineral Terraces — the natural architecture of the park
One of the main attractions visible on the camera is the mineral terraces, formed naturally over time. Hot mineralized water flows from the Big Spring, cools in the air, and deposits calcium carbonate (travertine), forming white-beige stepped terraces. This process has been ongoing for millennia, and today the terraces represent picturesque natural formations.
In the background of the camera, rocky hills with reddish and light-colored areas are visible — these are mineral deposits typical of the region's thermal springs. Each shade tells a story of the chemical processes occurring deep underground.
Monument Hill — the symbol of Thermopolis
At the top of one of the park's hills stands Monument Hill — a landmark of the town of Thermopolis. White stones on the hill spell out the inscription "World's Largest Mineral Hot Spring," which is visible from the town. This is not just a tourist attraction but a genuine reflection of the uniqueness of the local springs.
A trail leads to the top of the hill from the other side, passing through a bison pasture. From the summit, you can view the entire Bighorn River valley and appreciate the scale of the geothermal zone. The Hot Springs Park webcam partially captures this hill, allowing you to see it from a distance.
Koi Fish Pond — a warm oasis in the park
Among the green lawns of the park lies a pond with bright koi fish — one of the most attractive spots for visitors. The pond is fed by warm mineral water from the park's geothermal springs, creating a comfortable environment for the fish even during cold weather.
You can watch the koi at any time — the warm water prevents the pond from freezing even in the winter months, when temperatures in Wyoming drop well below zero. This makes the pond a year-round attraction for both tourists and local residents who come here to relax and observe the fish.
Bison Herd — living history of Wyoming
Hot Springs Park is home to the official bison herd of the state of Wyoming. This herd has been grazing in the park for over 100 years, making it one of the oldest protected bison populations in the United States. For the state of Wyoming, the bison holds special symbolic significance — it is depicted on the state flag.
In 2025, the herd numbered 30 individuals, with 13 cows having calved this year. In the fall or early winter, some of the animals (about 15 head) are sold at public auction, as the pasture area is limited. On the park webcam, you can sometimes spot bison grazing on the hills in the distance.
Bighorn River and the park's natural surroundings
Hot Springs Park is located in the Bighorn River valley, which flows through all of Thermopolis. The terrain is shaped by geothermal activity — in addition to hot springs, you can see geysers and fumaroles here. The river water is warmed by thermal springs, creating a unique ecosystem.
The landscape around the park is characteristic of Wyoming — open steppe spaces, hills with sparse vegetation, rocky outcrops. The camera shows the road leading to the park and electric poles — civilization blends harmoniously into the natural landscape without disrupting its pristine character.
Climate and seasonal features of Thermopolis
Thermopolis is located in central Wyoming, where the climate is characterized by sharp temperature swings. Summers here are warm and dry, winters are cold with moderate snowfall. However, the thermal springs create a local microclimate — it is always warmer around them, and in winter you can observe steam rising above the warm water against a backdrop of snow-covered hills.
It is in winter that the view of Hot Springs Park is most impressive: the contrast between the cold air and hot water creates a unique atmosphere. The mineral terraces become covered with frost, while the koi pond remains warm and full of life. The online webcam allows you to witness this beauty at any time of year.
Park infrastructure and tourist opportunities
Hot Springs Park is not only a natural attraction but also a full-fledged recreational area. There are walking paths, picnic spots, and observation decks. In the foreground of the camera, you can see a green grassy lawn with trees and a wooden fence — this is the well-maintained part of the park where visitors can relax.
The park's thermal waters are used for health treatments — Thermopolis has spa centers and balneological facilities. The mineral water, rich in various elements, is considered beneficial for health. Many tourists come here specifically for thermal baths and outdoor recreation.
What the camera shows
The Hot Springs Park webcam in Thermopolis broadcasts a view of the central part of the Wyoming state park. In the foreground — a green grassy lawn with several trees and a wooden fence. In the background, the characteristic landscape of the geothermal zone unfolds: mineral deposits, rocky hills with reddish and light-colored areas typical of the region's thermal springs. A road and an electric pole are visible. The park is located near geothermal formations and thermal springs, making this online camera a unique opportunity to observe natural processes in real time.
