Lodging at Orange Guest House. Turtle Cove lives up to its name as a favorite spot for giant marine turtles. Mustard rays are sometimes seen here in abundance, too. Visit Plazas islets, where land iguanas, looking like miniature yellow dinosaurs, lounge about under the Opuntia cacti that they feed on. Swallowtail gulls and other seabirds can be seen along the lava cliffs on the high side of South Plaza Islet, and, of course, sea lions are romping along the rocky shores.
Snorkeling is good along the shore of the channel separating North and South Plazas.
In the afternoon the Sulidae puts into port at Puerto Ayora on Santa Cruz Island, and you will visit the Charles Darwin Research Station to see the results of the giant tortoise and land iguana captive breeding projects. You'll also have a chance to do a bit of souvenir shopping in town. The lava herons, yellow-crowned night herons, and American oyster catchers also frequent these shores, and of course, sea lions and marine iguanas abound. The final stop before returning to Baltra harbor is at North Seymour Island, where more sea lions occupy the beach and sea birds nest along the trail through the island's brushy interior. Frigate birds, boobies, lava gulls, finches, and upon occasion, a whimbrel, can be seen here.
