The pristine shore of Passikudah is much sought after by those who prefer to escape to an isolated tropical heaven. The beach is wide and long; the waves are gentle and calm; there seems to be nothing for miles but pure white sands. Beneath the waters of the bay, a unique coral reef system thrives with myriad species of tropical fish. The shallow reef stretches far out and is connected to similar reefs at Kalkudah.

This is one of the best-known reef systems in the region and is now a proposed Marine Sanctuary.
