Great and Little Basses Reefs are located on the South East coast of the island, off the small fishing village Kirinda. Albeit being a natural barrier that protects the south eastern coastal belt, the Basses have also resulted in wrecking many ships that unsuspectingly sailed too close to the shore line. In 1873 and 1878, the ruling British government built two light houses in both reefs, which are still in operation
Diving in the Basses is a much anticipated activity. Due to strong currents and rough sea conditions, diving can be done only during mid March until the end of April each year, when the North East monsoons end, and South West monsoons are about to start.
