Our day began with a pre-breakfast kayaking outing at Chinese Hat, where we had the chance to learn about geological features like cinder cones, tuff cones, and lava flows that date back as far as 20,000 years ago. We also enjoyed a snorkeling excursion in the same area, and then we relocated National Geographic Islander II to the other side of Santiago Island at Sullivan Bay. Here, we hiked around frozen lava fields.
