Divers travel to Thailand for some of the best diving in the world on both coasts of the country. The Andaman Sea has one of the most coveted reefs with a world top 5 in Hin Daeng and Hin Muang off of Ko Lanta. The most beginner friendly diving in the world is in the Gulf of Thailand where the island of Ko Tao certifies more divers than anywhere else. Diving wise, what both sides have in common despite different ecosystems, is the opportunity to swim with the elusive, friendly, and very curious giant, the Whale Shark.
There aren’t any reefs that guarantee a Whale Shark sighting, and there are some dive masters that I met in Ko Tao, that despite diving every day, have yet to spot one. That said there is always excitement that grows on the diving boats that this dive might be the lucky one. In that case, abandon the dive game plan, and just hang around the Whale Shark being sure to give it space, especially around its tail.
