Roca Blanca - Galápagos Islands
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.
