Fodor's Expert Review Blue Hole

About 8,000 diving permits are issued per year for folks who strap on tanks and plunge into the 80-foot-deep artesian spring–fed pool at the Blue Hole, which is also open for public swimming during daylight hours (no fee). Cliff diving is great fun here, as is snorkeling and coming face to face with the many koi and goldfish that have been deposited here over the years.

Stella Salazar runs the dive shop (575/472–3370) adjacent to the Blue Hole; hours are generally restricted to the weekends, although the pool is open seven days a week. Tanks, air, weight belts, and a few other basics are available there. Weekly dive permits are $20; annual permits are $50.
