Welcome to Chom Ong Caves
Udomxai's top tourist attraction, the extensive cave system of Chom Ong Caves (ຖ້ຳຈອມອອງ) burrows more than 15km beneath a forested karst ridge near the Khamu village Ban Chom Ong, 48km from Udomxai. Often as high as 40m within, it's a veritable cathedral of a place whose first 450m have been lit with solar-powered lamps. Over millions of years the time-worn stalactites have been coated with curious crusts of minerals and sometimes studded with gravel from later wash-throughs. To gain access you'll need to borrow the gate-key and engage a guide (40,000K) in Ban Chom Ong, from which the cave entrance is an hour's walk.
