The district is located in the Khian Sa basin, which is crossed by the Tapi River, which also forms part of the eastern boundary of the district. The area of the district is mostly used for rice farming or rubber plantations, while along the river are swamps like the Nong Thung Thong swamp.
The main road through the district is Thailand Route 44, which connects Krabi with Khanom.
The district was formed as a minor district (king amphoe) on December 15, 1970, splitting the two tambon Khian Sa and Phuang Phromkhon from Ban Na San district [1]. On April 1, 1974 it was elevated to full district status[2].
The district is subdivided into 5 subdistricts (tambon), which in turn are further subdivided into 52 villages (muban). Khian Sa has township status (thesaban tambon), covering parts of the tambon Khian Sa. Each of the tambon is administrated by a Tambon administrative office (TAO).
