Millions of years ago, a big coral reef covered much of what is now South East Asia. Just as they do now, coral polyps living in the reef secreted limestone as they built the coral, and other marine critters like shells and urchins deposited calcium.
Fast forward a bit and the tectonic plates below started to rub against each other and rumble. The continents started to move. The reef was thrust skyward by the movement of big slabs of rock and the sea level started to change.
Fast forward a lot more and where there was a reef, there’s now hundreds of little islands. Rock pillars jutting straight out of the sea.
Fast forward a bit more to present day. The islands in Phang Nga Bay in Thailand are spectacular. But it’s what is hidden within that is most impressive. Weather and time have carved their way through the limestone rock to produce caves and inner lagoons. Karstic formations ripe for exploration!
