Barangay San Pedro is bounded on the North by Mindoro; on the East by Barraca, Paratong, and Bulala; on the West by the China Sea; on the South by the China Sea and Manangat River.
The barangay is divided into two sitios; San Pedro Norte and San Pedro Sur. The former are sometimes called “Nagtupakan” and the later is called “Cruz”. One of the sitios was called “Nagtupakan” because the place was suddenly inhabited by the people from Sta. Catalina, Ilocos Sur. The other sitio was called “Cruz” due to a wooden cross believed to have been planted by the Spanish colonizers in the place not very far from the sea.
The barangay as a whole is called San Pedro because the people being fisherman chose Saint Peter (San Pedro) as their patron Saint when the chapel was constructed in the place. It is to be recalled, in this connection, that Saint Peter was a fisherman, according to the Scriptures.

There is also an elementary school in the western part of the barangay. As the lifestyle of the people became more progressive, telephone and cable lines were also installed.
