Hin Muang and Hin Daeng are the deepest drop-offs in Thailand. They are world-class dive sites and provide some of the most stunning diving in the area, with a high chance of seeing Manta Rays and even Whale Sharks.

Located 70km south of Ko Lanta, they boast good visibility, unless the waters become extremely plankton-rich. It is this plankton that attracts the larger marine-life and there is a high chance of seeing Manta Rays and passing Whale Sharks throughout the season.

Hin Muang, ‘purple Rock’, is named after the beautiful purple corals that cover the pinnacles. The greater depths and currents make this site an ideal place to gain experience as you train to become a PADI Divemaster or PADI Dive Instructor.

From our location in the South of Ko Lanta, we can reach Lanta’s Top Dive Sites much quicker than dive boats that leave from Saladan in the North of the island. Our journey time to Hin Daeng & Hin Muang is just 1 hour (compared to 4 hours by big boat from Saladan). Take a look at our High-Speed Dive Cruiser to see why!

Hin Muang is completely submerged and derives its name from the vast number of purple corals covering the pinnacle. It is also known as a cleaning station for passing Manta Rays who come here to be cleaned and use neighboring dive site Hin Daeng as a navigation point.

The Hin Muang reef is 200 meters long and less than 20 meters wide, and comprises three main pinnacles and several smaller ones. There is a channel in the centre of the reef in which reef fish congregate to escape the currents that sweep along each side of the reef.

The top of the reef starts at 12m. Currents running over the top of the submerged pinnacles are usual, so we use a line for descent, safety stops and ascent.

At Hin Muang and Hin Daeng dive sites, the marine-life seems to be on a larger scale than elsewhere else in the Andaman Sea. Many Giant Morays can be seen amongst the cracks and crevices and large Leopard Sharks are often found lying on the sand in the 40-meter ridges.

It’s fascinating to watch the huge schools of Yellow Snappers and Fusiliers schooling around the tops of the pinnacles while Rainbow Runners, Jacks and Travellie dart in, hoping for a quick snack. The sheer volume of fish life is an amazing spectacle to witness.

Red-Tooth Trigger Fish flutter prettily amongst the the colourful soft corals, and many types of Anemone fish dance over the top of the highest pinnacles.

It’s here at Hin Muang, that the Manta Ray’s come to be cleaned by cleaner fish, darting about in the currents that sweep over the tops of the pinnacles. Facing in to the current, these graceful giants appear to hover, effortlessly while their obliging cleaners get to work on the parasites that inhabit their tough skin.

Due to the greater depths and currents (especially at Hin Muang), we recommend that these dives are suitable for Advanced Open Water divers or Open Water divers with twenty dives or more.

We keep group sizes small to ensure you get the most out of each fun dive. This also reduces impact on our reefs. Our emphasis is on safety, fun and personal service within a relaxed and stress-free environment. You will find the atmosphere and service on our dive boats, beyond anything you have experienced before!

Our experienced Divemasters know the dive sites extremely well, and will be happy to discuss what you would like to see, and the type of dive or snorkel experience you would like to have. Each dive is personally planned with the divers in each group, to ensure you enjoy each and every dive you make with us.
