Among the countless caves in Thailand, only but a fraction have been explored. New caves are being discovered almost every day.
How can a cave become lost? Landslides, violent storms, earthquakes, volcanic upheavals, and by the efforts of man himself. It's a known fact that caves for some reason or other are sealed by those who want to keep them secret, as the Japanese had done to many caves in Southeast Asia after their defeat in World War II.
Cave exploring in Southeast Asia is a relatively new sport, if we can call it a sport. Even the name can be misleading. Americans call cave exploring 'spelunking.' The British say it's 'speleology,' and they are correct if we use the Oxford English dictionary. On the other hand, Webster's defines a spelunker as one who explores or studies caves. Whatever the name, both are the same.
Spelunking is gradually making its way in Asia. The difficulty of cave exploring, however, is finding out what caves have been explored and which have not. Nevertheless, there is beyond any doubt, the caves and underground caverns of Thailand and the Malay Peninsula are the most challenging and interesting in the world. These caves hold many of mankind's most baffling secrets.
For the serious-minded speleologist, the caves of Thailand can offer adventure unchallenged, but only well equipped parties with experience can explore these caves properly and safely. On the other hand, caves marked on tourism maps can be visited by the casual traveller.
Cave exploring in Thailand has only begun, and holds untold possibilities for the adventure traveller. Even finding them can be an adventure.
