Las Tintoreras

Located along the southeastern Isabela island, west of Puerto Villamil, Los Tuneles is a complex of ancient lava formations in which an extraordinary abundance of life thrives. Over time, lava flows have created hundreds of tunnels and arches above and below the water, providing natural homes and ecosystems for blue footed boobies, white-tip sharks, sea lions, penguins, sea turtles—and seahorses. Organized snorkeling trips allow up-close encounters.
