The ideal underwater conditions of Thailand including its spectacular marine life make the Kingdom very popular among divers. In particular, liveaboard divers enjoy some of the best adventures with Manta rays and whale sharks including colourful coral reefs. If you want to experience this type of adventure, join Similan Island Liveaboard when the waters are its calmest so that you can reach the best sites.
However, diving in the open waters is totally different from cave diving. Cave diving is a technical activity that requires skills in open water scuba diving and rock climbing. According to Texas-based Bill Stone, a long time cave diver and expedition leader, as few as 75 people all over the world do serious cave diving. Stone who has been caving diving for 42 years said that cave diving is not a recreational sport.
Modern day cave diving grew from the need of people to explore. The simplest form of the activity is the spring dive where a diver straps on his scuba gear to journey down a clear flowing subterranean spring. This type of water adventure is quite popular in Florida and the Yucatan Peninsula.
Stone further estimates the number of people who are into cave diving as 10,000 from all over the world. The longest spring dive as recorded is 10 miles underwater, roundtrip. A more serious diver can try the sump dive that is performed into a cave where there is water. The water is usually murky with zero visibility. In some situations, the water is high enough to reach the ceiling. Professionals undertake this dive by getting from one dry chamber to another.
Because it is impossible to see, cave divers use a line similar to what mountaineers use. The line is a 2mm rope that is sturdy and heavy. The thrill for cave divers is to try to find something new by exploring.
Scuba diving is more of a recreational sport. You can dive from the Similan Island Liveaboard or you can just sit back and watch the action. However, before you do some serious diving, make sure that there is great visibility and lack of strong current to enjoy the underwater world.
