High Rock Liveaboard Diving

Location: Myanmar/Burma, Mergui Archipelago Myanmar/Burma, Mergui Archipelago

Myanmar's High Rock is in the southern area of the Mergui Archipelago and just 66 kilometres from Kawthoung. It's often chosen as a dive site to visit on the first day of a Myanmar liveaboard cruise. It sits alone out in the sea, 600 metres from Quoin Island, making it easy to spot and very photogenic. You can dive it once or more, depending on the currents and how quickly you want to swim along the reef.

Above the water's surface, High Rock is one of the most-recognizable dive sites of Burma's Mergui Archipelago. This is because it sits alone with a single Banyan Tree on top. Depending on the sea conditions and your dive plan, your liveaboard diving safari boat will moor slightly up current, or in the shelter of the island down current. Then after jumping in and doing a final buddy check, you can descend to the sandy bottom, 30 or so metres below the surface.

Alternatively, some divers want to see it all, and choose to circle the rock while ascending. Either way, you will be very impressed with the resident and visiting marine life here. Expect to see huge shoals of Snappers and predatory Trevally. Barracuda are often seen here, too. Down deep, there are nearly always several species of stingrays and sleeping sharks. There are some old and discarded fishing nets from decades past, and these have become home to many small species, especially seahorses. Keen scuba diving photographers can spend lots of time looking for, and taking pictures of, these macro species. Large pelagics do pass by from time to time, but this dive site is better known for large shoals of fish plus the seahorses and other critters.

Currents aren't usually too strong here, and they usually flow northeast to southwest or vice versa. Surface waves can be a bit of an issue at certain times of year, depending on the winds. Visibility is generally very good, but not spectacular. In any case, there's so much life here that it's not unheard of to not be able to see the wall on the eastern side because so many fish are in the way!
