North of the airport and Tumon, the snorkeling at Haputo Beach offers scenic coral and rock formations to explore. The beach access for Haputo Beach requires a short but steep hike down to reach from the road.
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. 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, Haputo Beach is the 16th most popular snorkel dive spot of all 17 snorkeling dives in Guam.
