Bulalacao is flanked by mountain ranges; the highest peak lies on the north. The area is well-drained and springs abound at its foothills along the border of the main rivers. Small creeks and rivers pre-occupied themselves with mangroves at the head of the bay. The area is largely limestone country with some very rugged terrain configurations. It has eight islets, two of which are not inhabited. These islets are potential tourism areas because of their long stretch of white sand beaches. They have interesting coral formations ideal for scuba diving and snorkeling.
