Ao Luek Tai (อ่าวลึกใต้) is a subdistrict of Ao Luek in Krabi. National-park information places Than Bok Khorani in Village 2, where the stream emerges through a hill-and-forest setting before continuing towards the coast.
The provincial cultural office also identifies Phi Hua To Cave in Village 6 of Ao Luek Tai. These are separate natural and heritage locations within a wider administrative area. Than Bok Khorani National Park extends beyond the tambon, so its islands, caves and visitor entrances should be checked individually rather than assigned the tambon's central point.
