The Tunnels is a large area in the western part of Isabela island, where over time, the volcanic lava flow has given way to the formation of lava tunnels in the ocean. Among the marine fauna, it is possible to see large manta rays, sea turtles, sharks, penguins, blue-footed boobies, and sea horses.  It is located 45 minutes from Puerto Villamil by boat and is one of the most impressive places for snorkeling. The tour consists of a short walk on the volcanic rock and a snorkeling activity.
