The agile Silver Galapagos can anchor in deep water right up against the cliffs of Punta Vicente Roca on the northwest side of Isabela Island. From our anchorage Zodiacs set out to cruise beneath the imposing volcanic coastline. The cliffs support endemic Flightless Cormorants, Galapagos fur seals, Blue-footed Boobies, and marine iguanas. The waters below hold scores of Eastern Pacific green sea turtles swimming all around the Zodiacs. If conditions allow, fortunate snorkelers will have an opportunity to swim with eagle rays, Galapagos sea lions, Galapagos Penguins, and schools of small tuna in the blue. Snorkeling in quiet coves and through a massive sea cave allows even more chances to experience this amazing environment.
