Exploring the Mergui Archipelago by liveaboard
The Mergui Archipelago in Myanmar is one of the most remote diving destinations in the Andaman Sea. With hundreds of islands, isolated reefs and spectacular underwater landscapes, a liveaboard is the perfect way to explore this untouched part of Myanmar. Diving here can reveal everything from schooling fish, rays and sharks to seahorses, frogfish and other fascinating marine life.
Day One
Departure from Ranong with a full cruise with 12 Divers was setting sail for Mergui again with a lovely dinner at sunset…

First destination was High Rock to where the group decided to claim the reef back as a dive site and for the marine life. A huge fishing net was covering the reef since November. Since we had a larger staff crew of 5 instructors and Dive masters on board we decided to claim the reef back with an early dive for the staff before bringing the guests to enjoy their morning dive. With the help of a lift bag, we managed to remove half of the ghost net from the reef and recover it to the surface and onboard the MV Thai Sea.The adventure continued with 2 exploration dives. We were very exited with our new discovery. Schools of travellies, tunas and and yellow finned barracudas circling our new dive site that the group decided to name “Name needed”.

Crystal clear waters awaited us for the morning dive at “North Twin Pinnacle”. Schools of Barracudas at the decent and Tunas hunting in the blue is what makes this dive site so special.

Black Rock never disappoints. On our 4 dives here we had Manta interaction with at least 3 Mantas, Schools of Barracudas as well as Tunas. The also enjoyed seeing the presence of sea snakes and Turtles. What else can you wish for?

There is a reason why this place is one of the more famous dive sites in Megui Archipelago . Bendstick Pipefish, Seahorses, Squid, Cuttle Fish, Marble Rays and 2 Ghostpipefish. A lot of tick marks in the dive logs! 😉

30m visibility at Western Rocky and the cuddle fish mating was underway with multiple love birds scattered around the rock. 2 Harlequin Shrimps and 10 frogfish were the highlights here. And of course the swimm through the western rocky cave.

New record for our seahorse spotters. We counted 11 smiling seahorses at Seahorse City. Great closing of an amazing cruise with amazing people.

Well done!!!
