Devils Hole is a small warm spring cave inside Ash Meadows National Wildlife Refuge, most noted for being the sole habitat for the critically endangered Devils Hole Pupfish.

Lying in an isolated area of the refuge, reaching Devils Hole requires a 0.2 mile walk on a closed dirt road to reach the viewing platform over the cavern. Between the small size of the Pupfish and the distance of the platform, visitors should bring binoculars if they'd like to see the fish.

Devils Hole is a part of the complex and deep network of limestone caverns and geothermal springs making up the desert oasis protected by the wildlife refuge designation. The Devils Hole Pupfish have been called the rarest fish in the world, with a population fewer than 200. Visitors will be struck by the amount of equipment and fencing present around the cavern. It's not the most unrestricted opportunity to view wildlife, however there it is a surreal feeling to be able to watch the endangered population of Pupfish at this distant corner of the Nevada desert.

Additionally, a trail continues up about a 100-foot incline to a protected opening to Devils Hole. There is really little to see here aside from the elevated view of the surrounding landscape.

The entire round trip walk is about 0.66 miles. There are no amenities of any kind at Devils Hole. 

Devils Hole, like Ash Meadows National Wildlife Refuge, is open daily from sunrise to sunset.
