Visiting these two islands are a perfect way to get a better understanding of the colonization and establishment of the unique flora and fauna of Galapagos. Both Islands have beautiful beaches you can enjoy, however, Bartolome Island and its parasitic volcanoes provide the best place to learn about the geology of this Archipelago. Rabida, on the other hand, provides good areas for water activities such as kayaking, paddle boarding, and snorkeling.
