About Ban Na Subdistrict
Ban Na (บ้านนา) belongs to Mueang Chumphon District, distinct from the same-named tambons in Songkhla and Surat Thani. The local-government plan describes plains and foothill land, with the Chumphon watercourse along the north, Khun Krathing to the east and the Ranong provincial boundary to the west. Wisai Nuea and Tham Sing lie along the southern side. Ban Na is a wider administrative area of village settlements, rather than a proposed railway location or a single community centre.
Include Mueang Chumphon and the actual village or host name in directions. Foothill destinations and properties on the town-facing side can require different approaches. The administrative coordinate does not identify a station, farm or local-authority entrance.
