Today is free for you to choose your own adventure on Isla Isabela. Ask your leader about the optional activities on offer – you might like to do something active, you could take a bus to the highest part of Isabela, where Sierra Negra Volcano is located, and take on a challenging 17-km hike up to the crater to see the spectacular views. If you’re lucky, you might even see the rare vermillion flycatcher. A worthwhile optional activity today is an excursion to Las Tintoreras, where white-tipped sharks rest during the day and marine iguanas nest. Otherwise, you could relax on the beach with a book, go for a swim or even do some snorkelling to discover what hidden wonders lie in Isla Isabela’s waters – you might see tropical fish, sea turtles or marine iguanas.
