Krabi: Southern Thailand's alluring natural beauty

Boat tours headed to nearby island archipelagos are popular attractions in Krabi. Travelers board modern speedboats or the traditional longtail boats for day trips into the scattering of fantasy islands.

Made of towering shafts of limestone, the islands were sea bottom and coral deposits over 225 million years ago. Today, they rise above the turquoise waters like castles.

The sedimentary rock is mostly light gray or white and other minerals and erosion add streaks of red, yellow, or even green. A typical boat tour stops in several places for swimming and snorkelling and offers a packed lunch on the beach.
