Neighboring sub-districts are (from the north clockwise): Ton Mamuang and Pho Rai Wan of Mueang Phetchaburi District and Tha Sen and Ban Lat of Ban Lat District. Most of the subdistrict consists of lowlands along the Phetchaburi River. An irrigation canal flows through Ban Samo Phlue, Ban Rai Kha, and Ban Don Phlap, providing water for agriculture.[1]
The Phetchaburi River flowing through Wat Tha Chaisiri temple is still believed to be "holy water", thus used in the coronation ceremony of the Thai monarchs of each period.[3]
