Lying just north of Baltra, Seymour is a small island formed of uplifted lava, covered in a forest of dwarf palo santo trees. The island is a breeding site for frigate birds, Nazca boobies and blue footed boobies. The tour takes you from the small dock on the coast, past a nesting ground for marine iguanas, and then to sites to observe the nests of the frigate birds, Nazca boobies and the blue footed boobies.

The tour then heads to Bachas beach, named such because of the abandoned WWII barges along the shore. This is a well-known nesting site for marine turtles, and it is sometimes possible to spot American flamingos in the lagoons behind the beach.
