Admired from afar, the shape of the island resembles a stone castle. At one end of the island is a natural stone gate which juts into the sea where a small boat can pass through. The area is where the Satun Aquaculture Office is located. On the other side of the island is a large U-shaped bay 700 meters wide. During the low tide, a cluster of corals can be seen aprallel with the shores.
Tourists can also visit the pearl culture farms.
Lidi islands are a haven for visitors who want privacy because the islands are small and uninhibited. The only buildings found on the island belong to the staff of a private company which has been granted a concession of the precious swallows' nests. Although there are thousands of swallows inhabiting the caves, their flocks cannot be seen easily because the caves where they nestle are accessible only bydiving along the narrow paths. The charm of Lidis lies on the twin islands of almost equal size and three or four islets to the south. Islanders can walk to explore the real, mysterious, and charming ambiance created by nature.
