Panglao is an island in the Philippines located in the Central Visayas. Politically, it is divided into two municipalities: Dauis and Panglao, both of Bohol Province. Panglao is located southwest of the island of Bohol and east of Cebu।

Panglao has a terrain that range from plain, hilly to mountainous. Panglao is made of Maribojoc Limestone, the youngest of the limestone units found in the western area of Bohol. The limestone composition halted the development of an airport as coralline limestone is soluble which causes formation of caves and sinkholes. One interesting geological feature found in the island is the Hinagdanan Cave which has an underground water source. The cave is an important water source as the island has no rivers or lakes.
