To reach the Guam snorkeling by air, fly into the Antonio B. Won Pat International Airport (GUM) which is located in the middle of the island.
While the dry season is typically January to June, the best snorkeling on Guam is during the months of May through August. The highest water clarity can be found if there is an incoming tide during the morning. 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.
