Welcome to A-One-Diving.com
A-One Diving has been operating from Ranong since 1999. A new branch opened in December 2001 on Koh Payam, a beautiful island set 2hrs. by boat from the main land. The settings are great, our multilingual team experienced and highly motivated, the Andaman Sea as prolific as promised : you won't forget your trip with us.
Our specialty : live-aboard. We propose a wide choice of diving trips (snorkellers are also welcome !) through the Thai Marine National Parks : Koh Similan, Koh Surin, Koh Tachai, and Koh Bon, also including the famous Richelieu Rock. the Mergui Archipelago are of course the highlights of our program.
