Our day began with a pre-breakfast climb on Bartholomew Island. We had the chance to learn about geological features like cinder cones and tuff cones, and we observed lava flows that date back no more than 200 years. We enjoyed snorkeling in the same area, and then we moved to another islet called Chinese Hat. We chose between snorkeling or touring around in a dinghy to observe Galapagos penguins.
