For those who want to spend a little more time "swimming with the fishes," Shark Reef now offers a longer program called the S.A.S. Adventure. It's a chance to learn Surface Air Snorkeling, involves using a "pony" tank and a small regulator as in SCUBA diving, as well as a buoyancy vest. There is an instructional overview and then you may spend a half-hour snorkeling. The fee is $20 per half-hour for the first person; $15 for the second person. Participants must be at least 5 years old. To sign up for the S.A.S. Adventure, and for more information, visit the kiosk near the entrance of Shark Reef.
