In the morning, enjoy a lovely hike to the Arnaldo Tupiza breeding center, located 1.2 km from Puerto Villamil. The trail passes through mangrove ecosystems, wetlands, lava fields, carob forests, and Manzanillo. Once you arrive at the center, you will be able to see several different species of giant tortoise that come from the Cerro Azul and Sierra Negra volcanoes. These species include Casserole, Five Hills, Roca Union, San Pedro, Five Hills, Caleta Iguana, Tables and Cerro Paloma.
In the afternoon, explore the amazing formations of lava along the seashore, created by the last eruptions of this volcanic island. This magical place has historically been filmed by BBC and National Geographic for their documentaries. It is a labyrinth of lava arches and crystal clear water full of sea turtles, eagle rays, sea lions, sharks and more. The turtles navigate their own highway from the mangroves to the open sea through "Los Tuneles". Here, you will have the best snorkeling opportunity with all these beautiful animals, including the curious Galapagos penguins. Before or after the trip, you can relax on the exotic white-sand beaches of Isabela Island.
