Phru Din Na (พรุดินนา) is a subdistrict of Khlong Thom in Krabi. The Land Development Department describes predominantly higher ground ranging from nearly level land to gently rolling terrain, with parts of the south in the Khao Pra–Bang Khram Wildlife Sanctuary setting.
Its waterways include Khlong Bang Bon, Khlong Lam Thap Phraek Tin, Khlong Chamueang and Huai Sok. Village names such as Khao Sam Nuai, Ban Dan, Thung Nui and Chong Siat help distinguish rural addresses across the tambon. Protected land and individual waterways have their own access conditions within this administrative landscape.
