Diana’s Punchbowl (Devil’s Cauldron): Remote Volcanic Crater in Nevada

Diana’s Punchbowl, also known as Devil’s Cauldron, is a volcanic crater filled with natural mineral water. It is located 72 miles southeast of the mountain town of Austin in the isolated Monitor Valley of central Nevada.

This remote geothermal site sits along a fault zone in Monitor Valley. The opening forms a large cavern about 50 feet wide, with vertical walls dropping roughly 30 feet.

At the bottom, a dark blue-green pool of scalding water up to 190°F (88°C) releases steam, gases, and hot vapor.

Native Americans have known about this remarkable place for thousands of years. The name “Devil’s” reflects early beliefs that spirits and mysterious forces inhabited the site.

Early visitors also picnicked on the slopes of the surrounding travertine hills while enjoying the dramatic views.

This geothermal area is better known for its dramatic natural landscape. However, smaller pools along the hot creek formed by overflow from Diana’s Punchbowl may offer opportunities for soaking.

As the water flows farther from the source, it cools to more comfortable bathing temperatures.

Several small dams have been built along the creek.

🔴 Warning: Use extreme caution near the crater edge and keep children at a safe distance. Dogs should be kept on a leash at all times.

Driving directly to the crater is not recommended for safety reasons. The opening may be difficult to see from a vehicle, especially at night or during rainy or foggy conditions.

Park near the cattle gate, close it behind you, and walk approximately 30 feet to the crater. The elevation gain is about 60 feet.

There are no restrooms, freshwater sources, or amenities on-site.

The nearest services are in Eureka, 68 miles away, and Austin, 72 miles away.

Please pack out all trash and follow Leave No Trace principles.
