Las Tintoreras is a chain of uninhabited islets that spreads across Isabela’s southern coast. Venture out on a two-hour hike through a mangrove forest and across dark black volcanic rocks. Search for whitetip reef sharks within crystal-clear pools of water. Look for endemic creatures such as the Galapagos marine iguana, the only species of iguana that dives under the water in search for food. After your hike, cool down and enjoy some time snorkeling as you look for sea lions, penguins, and other varied marine life.
