Santa Rosa Blue Hole
549 Lake Dr, Santa Rosa, NM
Santa Rosa, NM
A round pool of impossibly clear, cold spring water in the middle of the high plains, a scuba divers' mecca improbably parked on Route 66.
The Blue Hole is a nearly perfect circle of clear, cold water welling up from an artesian spring on the edge of Santa Rosa, its surface a startling turquoise-blue against the dun-colored plains. At the top it is only about eighty feet across, but it drops down a bell-shaped shaft to a depth of roughly eighty feet, and the water is so transparent that divers can see the walls falling away far below them.
Fed by a constant flow of fresh spring water, the pool refreshes itself continually and holds a steady, cool temperature all year. That combination of clarity, depth, and constant clean water has made it one of the most famous inland scuba diving destinations in the United States, a training spot for divers from across the region, sitting improbably beside old Route 66 in a small New Mexico town.
What Guests Love
- The astonishing clarity and deep blue color of the spring-fed water
- Watching scuba divers descend into a pool that seems to have no bottom
- A cool, refreshing swim in the desert on a hot day
- The classic Route 66 setting, an unexpected oasis just off the old road
Worth Knowing
- The water stays cold year-round, so a wetsuit helps for anything more than a quick dip
- Scuba diving requires a permit and proper certification, arranged through the town
- Swimming is at your own risk; there are no lifeguards, and the pool is very deep
- It is a popular local swimming and diving spot, so summer weekends can be busy

Learn about Santa Rosa Blue Hole
A spring in the plains
The Blue Hole is one of a chain of sinkholes and spring-fed lakes strung along this stretch of the Pecos country, which is why Santa Rosa calls itself the City of Natural Lakes. Beneath the surface lies a layer of soluble rock, and where groundwater has dissolved and collapsed that rock, deep circular openings have formed, filled and fed by the water table.
What sets the Blue Hole apart is its flow. Water rises through the pool from below and moves steadily, so the pool constantly renews itself with clean, cold water rather than sitting still and clouding. That continuous flow keeps the visibility remarkable and the temperature cool and even, no matter the season above.
A divers' mecca in the desert
The clarity and depth turned the Blue Hole into an unlikely capital of inland scuba diving. Far from any coast, it draws divers to train and certify in clear, controlled water, descending along the walls of the shaft where the light shifts from bright turquoise to deep blue. The town manages diving through a permit system to keep it safe and orderly.
For those who stay at the surface, the Blue Hole is simply a cold, clear swimming hole, a place to jump in and cool off in the desert heat. It is a rare thing, a landmark that serves both a serious diver working on certification and a family looking for a swim, all in the same round pool of spring water.
Route 66 and the town of Santa Rosa
Santa Rosa grew up as a railroad and highway town, and it sits squarely on old Route 66, the Mother Road that carried travelers across New Mexico for decades before the interstate. The Blue Hole became a natural stop, a splash of cool blue for road-trippers, and that Route 66 heritage still colors the town, from its old motels and diners to a well-loved auto museum.
The Pecos River and the surrounding lakes give the area a watery character unusual for the high plains, a landscape of fishing lakes, dam-fed reservoirs, and hidden sinkholes. Santa Rosa makes an easy, friendly overnight break on the long drive across the state, with the Blue Hole as its shining centerpiece.
When to go and what to expect
Because the water is cold year-round, summer is the most popular time for swimming, when the desert air is hot and the cool pool is at its most inviting. Divers come in every season, and the constant temperature means the underwater experience changes little through the year.
The setting is simple and low-key, a public pool ringed by rock with room to sit and watch. There are no lifeguards and the pool is genuinely deep, so caution is part of the visit, but for a swim, a dive, or just a look at that improbable blue in the middle of the plains, it is one of New Mexico's most memorable roadside stops.
