The erosion of limestone has formed the spectacular karst landscape in Krabi and Phang Nga Bay (once coral reefs hundreds of millions of years ago) due to the chemical weathering where acid rain, which produces carbonic acid, has dissolved layers of soluble bedrock. Karst landscapes feature limestone cliffs, caves, underground streams, and sinkholes.

The islands of Krabi and Phang Nga Bay were formed by the movements of massive plates of earth and lifted out of the seas. This geological process has created a landscape that really fascinates me, and I have been taking quite some pictures during my stays here. Check them out.
