Thailand is well known for its long stretch of coast and almost infinite number of possibilities for the adventurous spirit. As scuba evolved over time, the nation almost custom built itself, along with its many island destinations, for divers. There’s a lot to see here, and from corals to kelp forests it can suit the tastes of any diver.
Year Round, depending on location.
Thailand has fairly modern medical facilities for the region, but as most diving is done on outlying islands be sure that each dive site and boat is equipped with proper medical equipment before you go. Overall, Thailand is considered one of the safest places to travel.
Boat scams are pretty big. Don’t trust anyone who says that they’ll get you on the “last boat of the day” for a higher cost, and never assume the “seafood buffet” is going to be more than a few leftovers from the lunch served to paying customers at the restaurant they take you to. Stick to trusted, researched dive companies.
Food and lodging are fairly cheap in Thailand, which is great, because then you have plenty of cash left over to spend on scuba. Tours can range from the cheap end of $60USD to about $500USD for multiple wreck dives.
