Located far off the southwestern tip of the Baja Peninsula, the Revillagigedo archipelago consists of four volcanic islands known for their rocky shorelines. Many divers have nicknamed this region as the Mexican Galapagos due to marine life diversity. While snorkeling at Revillagigedo, you may encounter manta rays, galapagos sharks, clarion angelfish, moorish idols, angelfish and triggerfish.
Off the southwestern coast of Isla Socorro, there are two popular snorkeling dive spots including Double Pinnacle (aka Manta Rock) and the Tidepools (aka Aquarium). Isla Socorro is located about 22 miles to the southwest of Isla San Benedicto. While snorkeling at Double Pinnacle, you may encounter juvenile whitetipped reef sharks around the large boulders that are frequented by big moray eels. While snorkeling at Tidepools, you may encounter plentiful reef fish in a relatively calm pool.
The Revillagigedo archipelago is located about 220 miles to the southwest from Cabo San Lucas. The main way to get there is by live-aboard boat departing from Cabo San Lucas, and there are two regular dive boats heading out. It takes about 24 hours to reach the archipelago. With hurricanes from June to October and heavy seas from December to April, the best months for snorkeling conditions is November, April and May.
Overall, Isla Socorro is the 20th most popular snorkel dive spot of all 39 snorkeling dives in Mexico.
