The municipality of Mabini is a 32-kilometer stretch of rocky coastline with a land area of 4,296 hectares dominated by green hills and valleys. It is also characterized by a lack of rivers, so farmers need to rely on rainwater or wells for irrigation. The coastline is steep and the mountains fall abruptly in the ocean facing the Maricaban island in the south. In the North, Anilao connects after Bauan with the Taal volcano area.
