Chom Ong, Cave system in Oudomxay Province, Laos
The Chom Ong cave extends over 16 kilometers through a mountain ridge, featuring two main overlapping passages connected by a large central hall.
Initial scientific exploration of the cave system began in 2009, leading to measurements that established it as the longest cave in Northern Laos.
The local Khmu people of Ban Chom Ong village traditionally used the cave for bat hunting and guano collection, naming it 'Tam Chia' meaning Bat Cave.
The cave entrance requires a 45-minute walk from Ban Chom Ong village, which is accessible via a dirt road about 45 kilometers from Muang Xay.
The cave system contains two massive halls measuring 100 meters in length and 30 meters in width, with ceiling heights reaching between 30 to 50 meters.
