Have you ever been to Koh Tao? Diving is not even all you can do there. And Phuket is not all that makes Thailand The best time of the year for Koh Tao is from around Christmas to end of April. Later in the year, end of July until late September is also a great time. Whale Sharks come along there in March-April and in late summer.
The infrastructure of Koh Tao or translated ‘Turtle Island’ is meanwhile near perfect. Banks, ATM’s and loads of restaurants and bars from all nationalities. Parties going on a lot, like full moon parties half moon parties, black moon parties and so on
And if it’s not enough you have an hour ride on the boat and you are in Koh Phangan.
If you want a closer look, there are three places i can warmly recommend Asia Divers IDC Koh Tao at http://www.asia-divers.com for your Scuba Diving Instructor Training and Blue Diamond Dive Resort at the south end of Mae Haad, the’City’ of Koh Tao. their website is http://www.kohtao-scubadiving.com Nice people friendly and much much cheaper than Phuket, diving as well as eating out or renting a bungalow. Another very friendly Dive Center is Blue Marlin Dive Resort in Mae Haad. Have a look at their website here: http://www.bluemarlindiving.com/. Laid back atmosphere and chilled out scuba without stress. Plus totally cool three day trips to the Ang Thong Marine Park.
If you are looking for the very best in professional level scuba diving training you might want to have a look at Koh Tao IDC Thailand
I hope that i could give you an idea for your next scuba diving vacation.
If you have any specific question, don’t hesitate to ask.
Best regards, lots of air and big fish
