The Andaman Sea has thousands of square miles of pristine coral reef. Phuket Dive Tours is PADI (Professional Association of Diving Instructors) accredited and offers a broad range of experiences from instruction for beginners to overnight expeditions to the Similan Islands, an archipelago widely acknowledged as one of the world’s great diving destinations. Similan Island excursions range from two to four days. Nearer to Phuket, the Phi Phi Islands in the Hat Noppharat Thara – Mu Koh Phi Phi National Park provide exceptional snorkeling and scuba diving in the warm, crystal-clear waters. (Note that during the rainy season, the sea surrounding Phuket becomes cloudy, so the best time for diving is December through April.)
