Two small islands at the western end of the Princes' Islands. On dives that descend to 30-40 metres, purple seahorses and small underwater species are seen. The depth places them among the more advanced sites of the Adalar area.
Underwater cultural assets are covered by Turkish Law no. 2863. Diving at these sites is done only through authorized dive centers and in line with the published rules.
Distances are in a straight line and some coordinates are approximate; the route by boat is longer.
