Luka Tri Luke is situated in the bight formed by the coast of Otok Korčula between Rt Zaglav Veli (42°55′N 16°43′E) and Rt Ključ, about 2¼ miles W, from which a chain of four islets extends about 2 miles SE. At the NW head of the bight there are three small creeks accessible by boats. Anchorage may be obtained in the outer part of the bight in the fine season. Boats can find shelter in the three creeks at the head of the bight in depths of about 5 m, the most E being the least suitable; local knowledge is required; in a Bora hawsers to the shore are advised.
