Thailand Divesites



Similan Islands
| This movie shows diving in the Similan Islands and on the Tinminer Wreck |
'Koh' means 'island' in Thai, so most of the divesites
are named Koh ...
Koh Similian is a Marine National Park and located 90 km (52 NM - nautical miles) NW of Patong
Beach. (For the technical freaks amongst you - the coordinates
are on the Northern end
08º40'39" N and 97º39'15" E and 08º28'20" N and
97º39'40" E on the Southern end).
Perhaps the most famous of the dive sites in this area. This park
is a spectacular seven
mile long rocky archipelago, comprising of nine granite islands
set in the Andaman Ocean.
The resulting abundant collection of high-viz, multi level dive
sites are located near movie-location gorgeous islands
with tropical
rainforest, sandy beaches, and protected bays. Exploration of
the undeveloped islands is possible except for the vacation home
to some of the Thai Royals!
While diving, you are likely to discover an abundance of hard
and soft corals, diverse
marine life: large pelagic, including occasional whale
sharks, mantas or eagle rays. On the protected eastern sides of
the islands you'll find gentle sloping reefs, anemones, hard and
soft coral, and plenty of marine life.
On the western reefs you'll find giant boulder formations going
to below forty meters, including many tunnels, archways, caverns,
and swim throughs. Upwelling thermoclines from deep in the Indian
Ocean can sometimes make this a chilly dive for us warm-water
softies. Some of the sites have occasional moderate currents making
for challenging diving.
