Today we visited the largest island of the Galapagos Archipelago covering 58% of the Galapagos Islands total land mass, Isabela Island. In the morning we visited Urbina Bay where we enjoyed walking along male yellow iguanas and contemplating 6km upwelling terrain that occurred in 1954 when 5m of sea floor got uplifted. After a warm walk we got cool down with an open water swim from Urbina Bay beach to the ship. The rest of the day we had multiple activity options such as kayaking with sea lions, paddle boarding while we spotted sharks and snorkeling with fast swimming penguins and cormorants, yes you read that right, Galapagos swimming flightless cormorants. During a zodiac ride, Global Explorers collected plankton that we observed in the microscope and while aboard worked creating a new species of Galapagos fish using their creativity and all the knowledge they have acquired these days about fish. In the afternoon we hiked up to Tagus Cove to watch the sunset on top of Darwin Lake.
