Walk along the wetlands and appreciate the four species of coastal mangroves found among the brackish water lagoons. Observe the different species of waders, such as flamingos, stilts, gallinules, and whimbrels that feed in the area. The wetlands form a natural barrier protecting Puerto Villamil from waves and high tides. They are essential for the maintenance of biological diversity in the Galapagos. Several of the area’s inhabitants depend exclusively on the wetland to fulfill their life cycle, such as waders, crabs, land birds, and fish.
