Embark the Darwin Yacht, meet the Captain and crew, and set off to El Chato (Tortoise Reserve) in the afternoon. Follow the trail starting in Santa Rosa, which is surrounded by tall grass and borders the boundaries of some farms. Depending on the season, it can contain mud and slippery rocks. At 1 km there is a pool of water that is filled with tortoises during the rainy season. The road to the reserve is one of the best places to observe land birds. Tree and ground finches, vermilion flycatchers, and cattle egrets inhabit the area and sometimes Galapagos rails have been seen.
Spend the afternoon at the Isabela Wetlands, a complex of trails that includes Cerro Orchilla, a lookout which you can access via a staircase and from which you can see the bay and the town of Puerto Villamil, Sierra Negra Volcano, the Cerro Azul Volcano, islets, and rocks. Enjoy this spectacular scenery. Other trails at this site lead to picnic areas, mangrove forests, lava tubes, rocky beaches, and the Tortoise Breeding Center.
Dragon Hill, located in northwestern Santa Cruz Island, consists of a trail that runs through three different environments at just 1,600 m long. Its name is derived from the fact that in 1975, this site was one of the only places on Santa Cruz Island where there were land iguanas (Conolophus subcristatus) in a healthy state. In the lagoons at this site, there are shrimp (Artemia salina), the same as is the food of flamingos; at certain times of the year they are more abundant and therefore the population of these birds is larger. During rainier times the water of the lagoons becomes too sweet and therefore shellfish and shorebird populations decline.
In the afternoon, enjoy a non-motorized Panga ride in Black Turtle Cove, a mangrove estuary on the north coast of Santa Cruz Island. Many rays, sea turtles, pelicans, and others live in the mangroves.
Disembark the ship on Baltra for your flight back to the mainland.
