Settlements proliferate in the area fronted by the sand beach. Like in the other islands, shore erosion seems to be very active. Beach attrition has already affected a number of houses and the barangay hall. Agriculture is done in woody areas. There is a sizeable coconut plantation.
Fresh water is present in the form of shallow groundwater.
It is characterized by an expansive beach flat at the southern part and a rolling to gently sloping hill in the north. It is volcanic in origin, later enlarged by the deposition of the coastal plain at the southern part. The hill is moderately steep. The sandy flatland in the southern portion of Baguan makes up the largest part of the island. Fringing this flatland is a belt of coralline sand beach.
