Thailand's reputation as a diving destination is long-established and its western coast, met by the Andaman Sea, is where scuba divers flock to experience its finest dive sites.
This area is found to the south of Phuket Island and within the Mu Koh Lanta National Marine Park. Their proximity to Phuket means these sites can be dived via a short liveaboard trip, making them attractive to divers restricted by time or budget.
Hin Daeng is a favourite site for manta rays and even a whale shark to pass by. It is a submerged pinnacle covered with vibrant soft corals ringing its crown. Hin Muang is a much larger dive site and tends to be less crowded. Here you can dive Thailand's highest vertical wall and marvel at a vast carpet of anemones. Hin Muang is good for both big stuff like mantas, grey reef sharks and leopard sharks, schools of pelagics, but also for macro life too. [More details on these dive sites: Hin Daeng and Hin Muang].
The Phi Phi Islands are one of the best known destinations in Thailand, being amongst the most picturesque islands in the world. These islands and nearby Koh Ha are surrounded by many interesting caves and overhangs. Smaller marine life proliferates here such as clouds of glassfish, seahorses and shrimpfish, as well as leopard sharks and blacktip reef sharks.

Hin Daeng and Hin Muang - There are different options for diving this part of the Andaman Sea. Most divers who visit Thailand experience these dive sites as part of a liveabard safari called Similan, Richelieu Rock & Hin Daeng which takes in sites including Hin Daeng, Hin Muang, Koh Ha, Phi Phi Islands, Shark Point and Koh Dok Mai as well as the Similans, Koh Bon, Koh Tachai and Richelieu Rock. These cruises are for 5 or 6 nights.
If you are short of time or on a low budget, you can join a liveaboard tour to Phi Phi Islands, Hin Daeng & Hin Muang. These trips are usually only 3 nights in duration.
Currents can be strong but both Hin Daeng and Hi Muang offer plenty of shelter. Divers should be comfortable in the water and be able to manage some current. Hin Muang can at times represent quite a challenge since the current undergoes an increase in strength as it passes over the top of the rock.
