Situated on the northeastern portion of Espanola, Gardner Bay is a swimming and snorkeling site, with a beach that faces the islet of Gardner-near-Española. You'll have a wet landing amidst a large colony of sea lions.
Many visitors stay in one location, admiring and photographing the sea lions at close range. This seems to be the logical thing to do, especially since (and regrettably) many of the Guides sit on the sand and either read a book or talk with other Guides. What happens, though, is that you could miss seeing a Galapagos hawk at close range or a pair of American oystercatchers, Galapagos doves, 3 species of Darwin's finches, the endemic Hood mockingbird, yellow warblers, lava lizards, and marine iguanas. Do as you wish, but be aware of the possibilities.
Gardner Bay is an excellent place to check out your snorkeling equipment (especially for those who flew in to San Cristobal, as this could be your first full day). Once your check-out is complete, however, the really good snorkeling is off Gardner Islet (where there are a couple of neat caves and walls covered with invertebrates) and Tortuga Rock, the islet in the distance that, oddly enough, looks like a tortuga (turtle).
This visitor site lies at the west end of the island. The tourist trail is about 2km long and leads from one end of the island to the other while revealing the spectacular bird life.
A favorite of many tourists, Punta Suarez boasts the highest rate of endemism of all visitor sites. Sea lions, hawks, mockingbirds, blue-footed and masked boobies, red-billed tropicbirds, swallow-tailed gulls, waved albatross, doves, Sally Lightfoot crabs, lava lizards and marine iguanas can all be seen here. Between April and November, you can witness the unique mating rituals of the waved albatross and blue-footed boobies. The famous 'Blowhole' is toward the end of the trail.
There are so many blue-footed boobies nesting that have to take care not to step on one of their nests. You can observe red-green marine iguanas that are lying in the sun or the buzzards in the top of the trees. They hunt for young blue-footed boobies.
