Why dive here
With 131+ marine species recorded in the area - including dolphins, humpback whales, seals & sea lions, sea turtles and sperm whales - Roca Blanca offers some of Galápagos Islands's richest diving. Water ranges 23-28°C, warmest February, March, April.
Roca Blanca, off Isabela’s southeast coast, often gets a bit overshadowed by the big names, but we find it consistently delivers. It’s usually a relaxed drift, where you can watch Galapagos sharks, whitetips, and even hammerheads cruise by in the blue. Keep an eye out for the giant manta rays and their smaller eagle ray cousins, alongside playful sea lions zipping through the shoals of tropical fish. It’s a solid spot for divers who appreciate a consistent shark encounter without the often-gnarly currents of some other Galápagos sites.
Safety Notes
Strong currents typical this month (avg 36 cm/s). Good buoyancy control essential.
