Susan Hoi or Fossil Shells Beach
Situated at Ban Laem Pho, 17 kilometres from town. The area was once a large freshwater swamp, home to a kind of snail. Over eons dating from the Tertiary Age, about 40 million years ago, these snails lived and died by the millions.

Eventually, weather changes caused the swamp’s disappearance, but by then the layer of fossilised snail shells was 40 centimetres thick, resting on 10 centimetres of lignite below which is the subsoil. Because of geographic upheavals, the fossilised shells are now distributed in great broken sheets of impressive magnitude on the seashore at Laem Pho.
