West of the airport on the northwest coast of the Orote Peninsula, the snorkeling at Spanish Steps is quite popular with local divers for its marine life and beautiful scenery. This shallow cove is surrounded by tall cliffs and the walls of Orote Island protect the cove. During a Spanish Steps snorkeling dive, you may encounter jacks, octopus, clownfish and the occasional black-tipped reef shark.
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.
Note: the Spanish Steps snorkeling dive site is located on the US Navy Guam military installation which provides limited access from shore.
Overall, Spanish Steps is the 13th most popular snorkel dive spot of all 17 snorkeling dives in Guam.
