This website has information on the caves of Thailand that has been compiled over several years. It is hoped that this is of use to those interested in caving in the region and stimulates exploration in the country. I would be very interested in receiving any information (references, grid co-ordinates, reports, surveys, etc.) on Thai caves.

Cave explorer killed by carbon dioxide - July 2021

On Saturday 17 July 2021 Piyawee Tharasombat was killed by the high level of carbon dioxide in Tham Luuk. The cave is near Mu Si, Pak Chong district, Nakhon Ratchasima province. Local rescue services used breathing apparatus to recover the body of the 41-year old, which was found only 11 m from the bottom of the 5 m entrance ladder.

The cave is known for its bad air. On a visit in September 2017 Chaiporn Siripornpibul was unable to descend more than 3 m down the entrance shaft, with a cigarette lighter not working at this point due to the high carbon dioxide.
