Dream snorkeling around untouched and uninhabited islands

Santiago, Rabida and Bartolomé are wild, uninhabited islands that can only be accessed by boat, accompanied by a National Park guide. Staying overnight is not possible there. Santiago and Bartolomé are open to day tours starting from the neighboring Santa Cruz island, but only multi-day naturalist cruises can make a stop in Rabida.

Sea turtles and sea lions are some of the many species that can be observed around Rabida Island, located only a few kilometers south of Santiago Island.

Playa Espumilla, Puerto Egas, James Bay and Sullivan Bay are some of Santiago’s notable snorkel spots. Sullivan Bay is the most popular on the island; it faces Bartolomé island, another premium place for snorkelers. Rabida is a small island famous for its red sand beach, located less than 5km south of Santiago. Snorkeling is also possible along its shore.

Santiago offers gorgeous snorkeling explorations. Clear water ensures good underwater visibility and a great variety of species breed off its shores. Small penguin populations can be spotted around Santiago and Bartolomé islands, even if they are not as large as around Isabela Island. If lucky you might encounter them when snorkeling. Galápagos sea lions are numerous around the islands, especially next to Rabida, and you can be sure to swim with them during your journey. Green sea turtles are also unmissable around Santiago. Whitetip sharks, stingrays and spotted eagle rays can often be sighted, gliding over a sometimes starfish-packed seabed (seen in Bartolomé Island). Tropical fish lovers will be fully satisfied: king angelfish, parrotfish, butterflyfish and hawkfish also dwell here. If you plan a trip to the Galápagos islands, we recommend you bring with you the Wildlife of the Galápagos field guide, a compact and comprehensive identification guide to the unique wildlife you’ll encounter in the archipelago, both below and above the water.
