Hin Muang or ‘Purple Rock’ – is known as the Lanta Manta Cleaning Station and Whale Shark Navigation Point.

The dive sites Hin Daeng and Hin Muang 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.

From our location in the South of Ko Lanta, we can reach Lanta’s Top Dive Sites much faster than dive boats that depart 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!

The greater depths and currents make these sites suitable for Advanced divers or Open Water divers with 20+ dives.

Hin Muang, ‘Purple Rock’, is named after the beautiful purple corals that cover the pinnacles. Located 70km south of Ko Lanta, it boasts 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 is completely submerged and derives its name from the vast number of purple corals covering the pinnacle.

The reef is 200 meters long and less than 20 meters wide, there are three main pinnacles and several smaller ones. The reef starts at 12m, and there is often some current, so we use a line for descent, safety stops and ascent.

At these site, the marine-life seems to be on a larger scale than elsewhere in the Andaman Sea. Many Giant Morays can be seen amongst the cracks and crevices and large Leopard Sharks are often found in the 40-meter ridges.

It’s fascinating to watch the huge schools of Snappers and Fusiliers swim around the pinnacles while Rainbow Runners, Jacks and Travellie dart in, hoping for a quick snack.

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 is here that the Manta Ray’s come to be cleaned in the currents that sweep over the tops of the pinnacles.

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.

A full briefing is provided at each site, with helpful tips on what to look for, safety information, and the most interesting places to visit.
