Ash Meadows National Wildlife Refuge
Spring Meadows Rd
Amargosa Valley, NV
The largest oasis in the Mojave, where crystal-blue springs surface in the driest desert in North America and hold fish found nowhere else on earth.
Ash Meadows is the kind of place that should not exist. In the middle of the driest desert in North America, more than thirty seeps and springs push ancient water to the surface, feeding pools of an almost tropical blue and a chain of marshes and alkaline meadows across the valley floor. The water is fossil water, tens of thousands of years old, rising from a vast underground aquifer, and it has kept this oasis alive through the ages while the land around it turned to hardpan and creosote.
That isolation made Ash Meadows an evolutionary island. At least two dozen plants and animals live here and nowhere else on the planet, the highest concentration of endemic species in such a small area anywhere in the United States. The most famous is a tiny blue fish, the Devils Hole pupfish, that survives in a single water-filled cavern and has become one of the most closely watched endangered species in the world.
What Guests Love
- The unreal turquoise of Crystal Spring and the boardwalk that floats out over it
- Watching for the tiny endangered pupfish that live in a single warm pool and nowhere else
- Bird-rich wetlands set against bare desert mountains, a startling contrast
- How quiet and uncrowded it feels compared to the national park next door
Worth Knowing
- Devils Hole itself is fenced and can only be viewed from an overlook, to protect its pupfish
- Summer is brutally hot; spring and fall are the kind seasons, and winter brings the most birds
- Bring water, sun protection, and a full tank, as services out here are scarce
- Stay on the boardwalks and trails, since the springs and their species are extremely fragile

The story of the oasis
For thousands of years the springs of Ash Meadows sustained the Southern Paiute people, the Nuwuvi, who camped at the water, gathered mesquite and pinyon, and knew every seep by name. Their descendants, including the Timbisha Shoshone and Southern Paiute communities of the region, keep ties to this land today, and the refuge works with them to care for it.
In the twentieth century the oasis was very nearly destroyed. Ranchers and developers drained and channelized the springs for farming and, in the 1960s and 1970s, a large agricultural scheme began pumping groundwater so hard that the water level in Devils Hole dropped and the pupfish neared extinction. The fight to save them went all the way to the United States Supreme Court, which ruled in 1976 that the government's reservation of Devils Hole included the water needed to keep its fish alive, a landmark decision in Western water law.
To protect what was left, The Nature Conservancy bought the core of the oasis and, in 1984, it became a national wildlife refuge. Since then, managers have been slowly undoing the damage, filling in drainage ditches and letting the springs find their old channels again.
Devils Hole and the rarest fish
Devils Hole is a narrow, water-filled fault in the rock, a window into the aquifer that is more than five hundred feet deep and has never been fully explored. On a shallow rock shelf just below the surface lives the entire wild population of the Devils Hole pupfish, an inch-long, iridescent-blue fish that has lived in this one pool, cut off from all others, for tens of thousands of years.
The population is astonishingly small, often only a few dozen to a few hundred fish, which makes it one of the most vulnerable vertebrates on earth. Scientists monitor it constantly, even keeping a backup population in a purpose-built replica tank nearby. Devils Hole is a detached piece of Death Valley National Park, fenced off and viewable only from an overlook, so you cannot reach the water, but standing above that dark slot knowing what lives in it is its own kind of awe.
Springs, boardwalks, and what to see
The heart of a visit is the string of springs reached by short boardwalks and trails from the gravel refuge roads. Crystal Spring is the showstopper, a deep, clear, turquoise pool with a boardwalk that carries you out over the water. Longstreet Spring, Point of Rocks, and Kings Pool each have their own character, some framed by rock, some feeding reedy marshes alive with birdsong.
The modern visitor center explains the geology and the endemic species and is the best place to start. Because the water is a constant warm temperature year round, the springs never freeze and never dry up, so the oasis is green in every season.
Wildlife and the desert around it
Ash Meadows is one of the best birding spots in southern Nevada. The wetlands draw herons, egrets, ibis, and clouds of migrating ducks and shorebirds, while the surrounding desert holds roadrunners, phainopeplas, and raptors hunting the open flats. More than two hundred and fifty bird species have been recorded here.
Beyond the pupfish, the endemic list runs to other pupfish and springsnails, the Ash Meadows naucorid bug, and rare plants like the Ash Meadows blazing star and gumplant that grow in the alkaline soil. It is a living laboratory of how life adapts to isolation.
The land is stark and beautiful in every direction, with the Funeral Mountains and the ranges around Death Valley rising beyond the meadows.
When to go
Spring and fall are the best times to visit, with mild temperatures and, in spring, wildflowers and busy nesting birds. Winter is cool and quiet and brings the largest numbers of waterfowl. Summer temperatures regularly climb well past one hundred degrees, so a summer visit means early mornings and plenty of water.
The refuge is remote, so come with a full tank of gas, food, and sun protection, and plan to spend a few unhurried hours moving from spring to spring.
