Panglao has a terrain that range from plain, hilly to mountainous, composed by a limestone that is soluble and that causes the formation of caves and sinkholes. One interesting geological feature of the island is the "Hinagdanan Cave" which has an underground water source; because there no rivers or lakes in the island, the cave is an important water source.
