Dennis was our guide, and he made the whole day a great experience. He was friendly, funny, courteous, and very knowledgable about the island and it's history. Our day was carefree and a great way to see the majority of the island, when you don't have a lot of time. We stopped at so many gorgeous spots, and learned a lot about each one. Snorkeling with the sea turtles was great too! We consider it a day well spent!
