Diving in Thailand

Fringed by both the Andaman Sea and the Gulf of Thailand, this South-East Asian kingdom offers wonderful variety for diving. A country of Buddhist temples and tropical landscapes, it is also home to about 1,430 islands. Its amazing wildlife, ranging from elephants to whale sharks and the Asian water monitor lizard, also includes the only fish that walks on land, the blind, waterfall-climbing cavefish called Cryptotora thamicola.

Gloriously warm waters, multi-coloured coral reefs and rich marine life all make Thailand perfect for scuba diving. There is an amazing array of dive sites across the country and you can spot everything from big hitters, such as turtles, majestic manta rays and even whale sharks, to tiny seahorses and frogfish.
