Well signed beside Rte 3, 1.5km east of Nam Eng village, is this extensive, accessible cave system of which a 700m section is open to visitors. The main limestone formations include old stalactites encrusted with crystal deposits. Curious corrugations in the floor that now look like great old tree roots once formed the lips of carbonate pools like those at Turkey's Pamukkale. Local guides accompany visitors through the cave, but speak no English and have feeble torches. Extensive lighting is already wired up, but there are often power cuts, meaning a torch (flashlight) is a handy accessory. Allow around 45 minutes for the visit.
