We started our day by exploring Bartolomé Island, which is known for its geology. Once we were at the top we saw lots of geological features and parasitic volcanoes that are known as spatter cones, cinder cones, and tuff cones. In the afternoon we visited Rábida Island, which is one of the best islands in Galápagos for water activities (that have been permitted by the Galápagos National Park). It is also one of the most interesting red sandy beaches in this Archipelago.
