While snorkeling in Guam, keep an eye out for green sea turtles, hawksbill turtles and dozens of species of sharks. Overall, there are over 700 species of reef fish and over 300 species of coral on the fringing reefs. Most snorkelers stay within the fringing reef since there is usually a strong current just beyond the reef. There are a couple lesser well-known snorkeling dive sites off the east coast of Guam, which should only be attempted during the local summer months and then only with extreme care.
Overall, Fouha Bay is the 8th most popular snorkel dive spot of all 17 snorkeling dives in Guam.
