Ban Thamniap (บ้านทำเนียบ) is a subdistrict of Khiri Rat Nikhom in Surat Thani. The Tourism Authority identifies Ban Nam Rat headwater forest here, with a clear spring pool and a community setting focused on conserving its water source.
The same tourism account places Than Thong Waterfall in the tambon, while official education records identify schools at Ban Nam Rat and Ban Thamniap. These are individual places within a wider administrative area. The spring forest applies site-specific rules to protect the headwaters; consult current local arrangements for access rather than treating the tambon point as the attraction entrance.
