Shell Cemetery, also called Susan Hoi, is a fossil site near Ao Nang in Krabi. Its shore holds broad slabs of rock packed with fossilized gastropod shells, formed when the area was a shallow sea around 75 million years ago. Three zones let you look closely at the fossil beds, and a cliffside sea view adds a scenic stop to the visit. Go at low tide, when more of the formations are visible. This is a geology site, not a place for swimming or a beach day.
How the fossil beds formed
The shell layers date to a time when this part of Krabi was a shallow sea. Shellfish remains accumulated and became compressed into limestone, creating the broad fossil-bearing slabs visible along the shore. Look closely at the rock to find the shells preserved within it.
The fossils are identified as gastropod shells, including freshwater snails. Their presence in the stone gives the site its particular interest for visitors curious about geology and prehistoric life.
Exploring the site
The fossil formations are spread across three zones. A visitor centre provides background before you walk among the rock beds, helping put the visible remains in context. Paths are uneven, with rocky sections, so the site is not suitable for wheelchair access.
The shoreline is best viewed at low tide, when more of the fossil layers can be seen. At high tide, some formations are harder to appreciate. The site is not intended for swimming; focus on the rock beds and the sea outlook from the nearby cliff.
