The Buenavista Protected Landscape is an important watershed crossed by several rivers and streams such as the Mulanay River, Taisan Creek and Mahanao Creek which empty into the Sibuyan Sea. It is centered on Mount Maclayao (also known as Mount Kamhantik), the municipality's highest peak which rises to above sea level, in the sitio of Kamhantik in Barangay Buenavista. The protected area also contains several caves in the karst area extending to the village of Amuguis.
