The morning will consist of a visit to the Sierra Negra Volcano which is the largest basaltic caldera in the Galapagos with a diameter of 6.2 miles (10 km). The site offers impressive views and the opportunity to observe up to seven species of finches and a rich display of vegetation. The north side of the caldera provides evidence of its most recent volcanic activity in 2005.
In the afternoon you will visit The Wall of Tears (El Muro de las Lágrimas) which is 65 feet (25 meters) high and an important piece of the island history. A penal colony existed on Isabela from 1945-1959, and the prisoners were forced to build the wall, stone by stone, while in isolation from the rest of the world, and thousands died during the construction. Many claim to feel the heavy energy of this
historical site, and locals claim to hear cries in the wind.
Afterwards you will head to the Wetlands of Isabela Island which are located just outside of Puerto Villamil. The Wetlands consist of lagoons, swamps, and mangroves and are home to a variety of unique bird species such as common stilts, whimbrels, white-cheeked pintails, and gallinules. The Wetlands can be visited on foot via a path through the swamps.
Next you will visit Arnaldo Tupiza Breeding Center of Isabela. It is located about one mile (1.5 km) from Puerto Villamil. In this breeding center, populations from South Isabela Sierra Negra Volcano, Cerro Azul, Cazuela, Cinco Cerros, Roca Union, San Pedro, Tables and Cerro Paloma have been bred in captivity. In total there are 330 juvenile and adult tortoises.
