Koh Bon - Koh Tachai

Koh Bon and Koh Tachai are two tiny islands that lie between the Surins and the Similan Archipelago. Surrounded by deep waters, they're often visited by numerous pelagics. Manta rays are not a rare sighting there…
Interesting underwater topographies, arches, swim-through and often extremely good visibility : those two rocky islets deserve their reputation.
Koh Surin
The Surin islands offer a wide variety of diving and snorkelling sites, from the huge granite boulders so typical of the Andaman, to the underwater gardens of extremely well preserved hard coral. Turtles, eagle rays, are common encounters. The islands are also the perfect setting for some relaxation after a long day bubbling around. White sand beaches, green jungle, sea eagles circling in the sky… you can, at last, rest your eyes… [ click to enlarge Surin map ]
Richelieu Rock
The famous Richelieu Rock is actually a group of big pinnacles covered by beautiful purple soft coral. A lot of fish activity here, due to the deep waters around and the often-fair current : huge schools of big eye trevallies, barracudas, breams and yellow-striped snappers give the site a truly magical atmosphere.
Visibility can be spectacular, and large pelagics, like mantas and whale sharks, are regularly spotted.
Koh Similan
The Similan islands gather an extended range of world-class dive sites. Fish life there is the most varied of Thailand and reef sharks, turtles and rays make regular appearances. The coral is healthy and abundant : gorgonians, dendronephthyas, shelter hips of invertebrates. Shall we talk, again, about the excellent visibility that the mainly rocky bottom provides? Definitely, the nine islands offer enough to justify a whole trip, and every nature lover will be satisfied. [ click to enlarge Similan map ]
Koh Payam
Photographers, grab your macro lenses ! The green waters of Koh Payam will give you the perfect way to practice your "muck diving" skills… Numerous kinds of nudibranchs, flat worms, ascidians, sponges and colorful soft corals, hips of juvenile fishes and even several species of sea horses are guaranteed here if you possess sharp eyes.
