Isabela (Albemarle) Island is the largest of the Galapagos Islands. Located in the western part of the archipelago, Isabela is larger than all of the rest of the islands combined. Comprising six volcanoes, the island is about 75 miles long and covers 1771 square miles. Most visitor sites are on the western side of the island, far from Santa Cruz, so only the longer (more expensive) boat tours visit this island. It has three main landing points; Punta Vicente Roca, Tagus Cove and Urbina Bay. Isabela is known for its penguins, flightless cormorants, marine iguanas, boobies, pelicans and Sally light foot crabs.
