Today we get to know both the National Park and the Marine Reserve, each with their own unique features. After breakfast, start out at the Tintoreras visitor site, a small group of islets reachable only by boat, to observe reef sharks in their natural habitat, intertidal organisms, marine iguanas, and a colony of Galapagos penguins. Lunch at the lodge. Later in the day, we can explore the history of Isabela Island at the Wall of Tears visitor site. Sunsets at Puerto Villamil are spectacular. Dinner and overnight at Scalesia Lodge.
