It is one of the spots most favoured by the world tourism of today.

It is located at a distance of 15 kms from the center of the town. It is surrounded in the east by Kidrak and the Valley of Butterflies and, in the west, by Gemile and coves at the mouth of the valleys descending from the foot of Babadag.

The sand and pebbles of the vast coastline of the Belcekiz beach, carried in the direction of northwest by the waves and the wind, create a barrier between the open sea and the calm lagoon.That is why the region is called Ölüdeniz, meaning still as a cadaver.

The lagoon reaches a depth of approximately 40 meters towards the north, while it becomes shallow, down to 5 to 1 meters, in the southern part.
