Isabela Island is the largest of the Galapagos islands, on the western end of the archipelago. Shaped like a seahorse when viewed from above, Isabela is home to more wild tortoises than any other island, as well as a wide variety of other animal, bird and marine life.

On Isabela's west coast lies Tagus Cove, a natural protected harbor where centuries ago whalers safely spent the night and left their ships' signatures painted on the rocks. Near Elizabeth Bay, Moreno Point is a birdwatcher's delight. Further inland, visitors will find six volcanoes, five of which are still active and two that sit directly on the Equator. At the base of Alcedo Volcano is Urbina Bay, a perfect spot for snorkeling and home to the biggest land iguanas in the Galapagos.

To the north, located at the "mouth" of the island, is Punta Vicente Roca. Although it's a marine-only site (meaning it can only be accessed via dinghy or SCUBA diving), the formation nonetheless draws plenty of visitors eager to see its spectacular sea life - penguins, seahorses, sea turtles, sunfish, and more.
