Uvala Luka is entered between Rt Križ (42°57′⋅5N 17°09′⋅0E) and a point about 230 meters SW. An above-water rock (uncharted) stands near the outer edge of a shallow bank at the head of the inlet. Anchorage may be obtained W of the 48 m peak on the E side, noting that a submarine pipeline is laid from the inlet NNE across Pelješki Kanal. A small islet lies close to the E shore in the S part of the inlet. The sandy bottom is not reliable everywhere, however S of the above-water rock vessels may anchor in a depth of about 5 m, mud, good holding.
