REEF Field Survey Trips are eco-vacations led by marine life experts. Each trip features daily dives and fish ID classes for both beginners and experienced surveyors. Divers, snorkelers, and families are all welcome. Only a few spaces remain on our Field Survey Trip to the Southern Sea of Cortez, happening this fall from Sept. 29-Oct. 6. Warm waters and calm seas make this a great time of year to dive in the Sea of Cortez. This unique body of water is separated from the Pacific Ocean by Mexico's Baja Peninsula. This relatively isolated area (through easily accessible for travel) is known for interesting diving on rocky reefs and pinnacles, plus the chance to observe rarely seen marine life. Divers frequently enjoy seeing endemic species of fish, sea lions, sharks, rays, and more!
