Situated against the impressive backdrop of the Map Ta Put oil refinery, Sia Thong Beach can be categorised as a working beach. At the entrance to the beach there is a small natural harbour, with many small fishing vessels moored there. There is also a single, Thai style restaurant, mainly servicing the workers at the nearby refinery.
The beach itself is quite impressive, stretching for a couple of kilometres back toward Ban Chang. As there are no amenities and little shelter from the sun around the beach, you would be lucky to encounter another soul along its shores.
