Sai Khao (ทรายขาว) is a subdistrict of Khlong Thom in southern Krabi. The municipality describes generally flat land descending towards the west and adjoining the Andaman Sea.
Its administrative neighbours include Khlong Phon to the north and west and Kalase in Sikao District, Trang, towards the south and east. These boundaries place the tambon near the provincial coastal transition, rather than at an inland namesake elsewhere in Thailand. Use a specific village or shoreline locality to identify a destination; the administrative reference point does not establish beach access or a boat departure place.
