Thermopolis is a town in Wyoming, United States. It is the main town and county seat of Hot Springs County. In 2020, about 2,725 people lived there.

The name "Thermopolis" comes from Greek words meaning "hot city." This is because the town has many natural hot springs. These springs have mineral-rich water heated deep underground.

One of the most famous spots is "The Big Spring" in Hot Springs State Park. It is said to be the world's largest mineral hot spring. You can visit these springs for free. This was part of a special agreement made in 1896 with the Shoshone and Arapaho Native American tribes.

In 1993, dinosaur fossils were found nearby. This led to the creation of the Wyoming Dinosaur Center, a museum where you can see these amazing finds.

Exploring Thermopolis's Location

Thermopolis is located in a unique area of Wyoming. It sits near the northern end of the Wind River Canyon. This is where the Wind River changes its name to the Bighorn River. This change happens without two rivers joining, which is quite rare! People call this spot the "Wedding of the Waters."
