Blue Hole

Blue Hole is a natural spring in Santa Rosa, New Mexico, fed by underground water from a deep layer. The opening measures about 80 feet across at the surface and reaches a depth of around 130 feet, with the water staying at a steady 62 degrees Fahrenheit.

Before the spring became a public recreation area, it served as a fish hatchery for the region. Nomadic groups used the water as a reliable source while traveling through New Mexico.

The pool takes its name from the deep blue tint of the water, which comes from minerals in the underground layers. Divers from different regions come here to train in the clear conditions and improve their skills.

The site has a visitor area with changing rooms, restroom facilities, and picnic spots for swimmers and guests. Access for diving activities is regulated and requires proper certification.

An underground system renews all the water in the pool about four times a day through constant flow from the Ogallala Aquifer. This continuous renewal creates remarkably clear visibility underwater.
