Near where the western shoreline of Isabela bends sharply toward the lower arm of the island, there’s a visitor site that’s known for its marine life. Elizabeth Bay is best visited by a panga ride, as there are no landing sites. Marine turtles and rays can usually be seen in the water, and various seabirds and shorebirds are often present. Islas Mariela, at the entrance of the bay, are frequented by penguins.
