Tham Nang Aen

Cave in Tha Khaek

The last cave along this stretch of Rte 12 is the touristy Tham Nang Aen, about 18km from Tha Khaek. It's well lit inside, but a little kitsch in terms of the colour scheme. It is also possible to take a small boat deeper into the cave via an underground river.

The turn-off to the cave is indicated by a clear sign just past a left-hand bend 16km from the junction with Rte 13. The 700m-long track should be passable at all but the wettest times.
