Koh Larn Pattaya is the largest of the three inner islands, it has a quite number of good dive sites which are all very popular. Shark point derives its name from the juvenile nurse sharks that can be spotted hiding in holes and crevices on the reef. Hard and soft corals drop from the surface down to around about 24 meters where a sandy bottom takes over. The drop off on the western side has a series of coral ledges down to around 18 meters and continues down to over 40 meters although there is nothing to be seen at that depth. To the south of the island is Koh Larn Vac where there is the remains a sunken restaurant also over the past couple of years the Thai Navy decided to place a second world war ship, which is a great wreck for novice divers to look at.This area can be subject to a few tidal currents which on occasions can be strong Great for Padi Advanced open Water courses.
Laem Tong, set off to the North West of the island just which is part of a cliff face, in our opinion is probably the best dive of all the islands and only a short way from the wreck HTMS Kut, a terrific dive for the more experience and advanced diver sitting approximately 30 meters . At Laem Tong you will find an area with flat sandy bottoms and many large coral heads and groupings, plenty of small juvenile fish tend to populate this area with fairly large coral reef leading to an underwater rock face dropping to approx. 18 meters. This is a great and interesting area to explore, for both scuba divers, snorkelers and swimmers searching different types of marine life. Here you will find numerous amounts of Giant Sea Anemones with their inhabitants as well as a variety of Elephant Ear Anemones and the Black and White Clown Fish. Many divers may have seen these clown fish and observed their habit of disappearing into the mouth of the anemone as the divers approach. These types of fish make very good photographic subjects. In some of the deeper areas there are almost always Bamboo sharks to be found also Blue Spotted Sting Rays and Turtles.
This whole area is a great diving and snorkelling predominantly all year round as it’s quite well sheltered, although the best time to dive these sites are from October to February when the winds blow from the North. However during this time of the year unfortunately there are quite a number of speed boats and jet ski’s, As everybody tends to come to the island, This really is not a problem divers just need to be a little careful. So please do not let this put you off as this is still a great dive site and well worth it a great day out.
