Southwest of Guam International Airport and Agat, the snorkeling at Coral Gardens near the inner side of Anae Island is a popular shallow reef to explore. There are beautiful sea anemones and massive coral pillars that are teeming with diverse marine life. During Coral Garden snorkeling, you may encounter squirrelfish, moray eels, starfish, soldierfish, spinner dolphins and resting white-tipped reef sharks in waters from 5 to 50 feet deep.
To reach Coral Gardens by boat, use the boat launch located at the north end of Nimitz Beach or Agat Marina. The boat-accessed Coral Gardens snorkeling dive site is located in the large channel flowing past Anae Island running into Facpi Bay. The best time of day for Coral Gardens snorkeling is slack high tide for the highest visibility.
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.
TIP: Make sure to watch out for the trade winds. They are known to push the stinging man-o-wars into these waters.
Overall, Coral Gardens is the 4th most popular snorkel dive spot of all 17 snorkeling dives in Guam.
