I can only recommend Sub Aqua in Karon. I arranged my diving trip only after arriving at 10pm still Karren was reachable and we quickly agreed on the program for the next day. Although it was only an on shore dive at neighboring Katu beach I felt in good hands with dive master Marc who has excellent knowledge of the area. He never pushed the limits (the weather in the morning was a bit choppy) which is a good basis to start. I will certainly return when I'm in the area again to explore the offshore areas around Phuket.
