Embark on a must-do day trip to one of the most bio diverse sites in Galapagos. Los Tuneles, also known as Cabo Rosa, is an uninhabited islet located 1 hour from Puerto Villamil, Isabela Island. These lava formations look like tunnels and along hundreds of years have become a marine paradise inhabited by varied endemic Galapagos species.

This site is home to sea turtles, albatrosses, flamingos, iguanas, sea lions, blue-footed boobies, royal frigate, manta rays, penguins, sea lions, sea turtles, a variety of birds, lobsters, sea snakes, among other species. An exciting day trip to an iconic Galapagos site.
