Our first excursion off the boat was snorkeling off Seymour Island, not far from Baltra. The water was a little cold, but not too bad. Some members of our group opted for the available wet suit rentals, but we didn't, and it was okay. We saw a number of colorful tropical fish, sometimes in large schools. More fish than snorkeling in Bermuda, but not near as many as in the Red Sea in Egypt. One member of our group found some sea lions while snorkeling but we didn't see any.
