It is located on the southern edge of a river estuary south of the city of Varna on the Black Sea coast.

A seaplane base at Peinerdzhika (or Peynerdjik) was established by the Imperial German Navy Air Service and opened in early spring 1916 during World War I.

On 9 June 2017, during a training mission of artillery fire against surface targets as a part of the Bulgarian Navy's "Black Sea-2017" exercises, a Panther helicopter crashed in the water, killing the commander and injuring the other two officers on board.

The helicopter's main rotor made contact with the fore flagpole of the frigate BGS-41 Drazki, sending it into the sea.
