Costinesti is a commune and resort in Constanta County, Romania, located on the shore of the Black Sea, about 30 kilometers south of the county seat, Constanta. In the 1960s, it evolved from a small fishing village to a summer destination, most popular with young people and students. A hotel, as well as several villa complexes, were erected during the Communist era, and featured varying degrees of style and comfort. Since the Romanian Revolution of 1989, some of them have been modernized, and private construction, especially to the north of the resort, has taken off.
The resort also has a small inland lake, around which several lodges are located. Opposite to one of the northern beaches, the shipwreck of Evangelia, a Greek ship (originally a Liberty ship) beached there in the late 1960s, has proven quite popular with the tourists. Nightlife is centered mainly around the two discos (Ring and Tineretului), in which, during the summer months, concerts are held nightly by the most popular bands from across Romania. Because Costinesti is mostly frequented by youngsters, the atmosphere tends to be livelier than in the other Black Sea resorts.
Costinesti is easily accessible, either by train or car. There are two railway stops within the resort (South Costinesti — Tabara, North Costinesti), and the town is connected to the main E87 road which runs north to Constanta and south to the Bulgarian border.
