It’s easy to spot—just look for the colorful travertine terraces and the steady rise of geothermal steam.

Whether you're interested in geology, history, or simply unwinding in a natural setting, this unique destination has something for everyone.

Top Things to See and Do at Hot Springs State Park

Mineral-rich water flows from the spring at a constant 135°F (57°C), with more than 18,000 gallons emerging from the ground each day.

Fun fact: Native American tribes called the springs "Bah Cdewana," which means "smoking water." As early as 1875, Dr. Thomas G. Maghee—a pioneer in plastic surgery—wrote about the healing properties of these waters.

Colorful Terraces and Tepee Fountain
