What is the Blue Hole in New Mexico?
The Santa Rosa Blue Hole formation is one of several classic karst formations lying within a six-mile-wide subsidence feature known as the Santa Rosa sink in the Pecos River basin. The Blue Hole is just one of the roughly 190 gypsum- and limestone-solution sinks that pepper this area.
As with many other sinks in this area, the Blue Hole formed when groundwater from the western edge of the Ogallala Aquifer dissolved subterranean rock into a collapsed cave system, leaving a cenote (a sinkhole which exposes groundwater to the sky).
Other lakes near Santa Rosa, known as the “City of Natural Lakes,” are much larger. However, New Mexico’s Blue Hole is a popular destination for swimming and cliff jumping, and it’s also a sought-after location for altitude-adjusted scuba training.

Though there are no lifeguards on duty, warning signs and flotation rings are posted for safety. Freshwater snorkeling is also popular, thanks to this spring-fed swimming hole’s calm, current-free conditions and high visibility.
History and Local Lore
The Blue Hole’s story stretches back thousands of years. Indigenous peoples and early Spanish settlers valued this spring as a water source long before Santa Rosa was established. As the Santa Fe Trail developed, more travelers from the east began arriving along Beale’s Road (now Route 66) and found the swimming hole (then known as Blue Lake) a good pit stop.
Cowboys driving cattle across the Pecos River often stopped here, and legend has it Billy the Kid took a dip before riding into Santa Rosa.
In the early 1900s, town developers recognized the pool’s potential and used it as a fish hatchery. Later, in the 1970s, it gained popularity as a swimming and diving site, coinciding with the rise of tourism to Route 66 attractions. Local folklore spoke of hidden cave systems and deep, unexplored waters, a mystery that still fascinates divers.
Mystery at Blue Hole, New Mexico
Blue Hole in Santa Rosa, New Mexico, is famous for its deep blue waters and mysterious underwater cave system. In 1976, two student divers became lost in its tunnels; only one was recovered quickly, while the other’s body took weeks to find. Authorities sealed the caves, adding to the mystique.
Decades later, exploration teams reopened and mapped part of the dangerous, pitch-black system, but tragedy struck again in 2016 when a diver perished. Today, the caves remain sealed, leaving the Blue Hole’s hidden depths an enduring mystery.

Blue Hole New Mexico FAQs
Yes, beginners can dive at Blue Hole, but they must hold a valid open-water scuba certification from a recognized agency like PADI or SSI before entering the water. Uncertified individuals cannot rent gear or dive without a certified instructor. The basin is a premier training site featuring submerged platforms at various depths, calm freshwater conditions, and minimal currents. However, novice divers must account for high-altitude diving adjustments, as Santa Rosa sits over 4,500 feet above sea level, requiring specific decompression schedules and altitude gas management protocols during training.
No, recreational fishing is strictly prohibited inside the main Blue Hole basin to protect the clear water quality, aquatic ecosystem, and safety of swimmers and divers. However, nearby fishing options exist within the city. Youth anglers 11 and under, seniors 65 and older, and licensed individuals with disabilities can fish at the adjacent Blue Hole Kids Fishing Pond, which is seasonally stocked with catfish. Full-scale public fishing for bass, walleye, and catfish is available a short drive away at Santa Rosa Lake State Park.
