If you are visiting Krabi or Ao Nang be sure to make time to visit the famous Fossil Shell Beach, which is only 17 kilometres from downtown Krabi.

Around 40 million years ago the area was once a freshwater marsh that was mainly populated by just two centimetre long pond snails and small clams.

Due to the numerous dead shells a unique structured floor of fossils was created that measures over 40 centre metres in thickness, called shelly limestone.
