The province is a popular tourist destination with its beaches and resorts. The Chocolate Hills, numerous mounds of brown-coloured limestone formations, are the most popular attraction. The formations can be seen by land (climbing the highest point) or by air via ultralight air tours. Panglao Island, located just southwest of Tagbilaran, is famous for its diving locations and is routinely listed as one of the top ten diving locations in the world. Numerous tourist resorts and dive centers dot the southern beaches. The Philippine tarsier, amongst the world’s smallest primates, is indigenous to the island.
