Kalpitiya was a Portuguese and then Dutch fort town controlling the pearl and cinnamon coast, and the fort is still standing. The Bar Reef was declared a marine sanctuary in 1992 and is the largest protected reef in Sri Lanka. Anchorage: The Kalpitiya lagoon is a sheltered inland sea behind a long peninsula, and the reef lies outside it. Hazards: The reef bleached badly in 1998 and again in 2016, so expect recovery rather than a postcard; current on the outer edge. More
