Today we visited the largest island of the Galapagos archipelago, making up 58 percent of the total land mass—Isabela Island. In the morning we visited Urbina Bay, where we walked on upwelled terrain that occurred in 1954 due to volcanic activity. In this new area, we spotted our first group of Galapagos giant tortoises from Alcedo Volcano, standing by the trail. We also encountered lots of male yellow land iguanas. After a warm walk, we had the chance to cool down, swimming with penguins and sea turtles. For the rest of the day, we had multiple activities at Tagus Cove such as kayaking, paddle-boarding, snorkeling and Zodiac cruising. There was so much wildlife to be seen, and we spotted sea lions, pelicans, penguins and flightless cormorants. Another wonderful day in paradise onboard National Geographic Endeavour II.
