The Danube Delta

Surface: 5050 km ²  (of which 4340 km ² in Romania and 710 km ²  in Ukraine), together with the flooded areas, sand banks and complex lagoon Razim - Sinoe.

The Delta area, formed in Quaternary period, in close connection with the variation of the Black Sea and the intake of rich alluvial Delta, has the appearance of a giant equilateral triangle, with sides of c.80 km each.

At Ismail, the Danube is divided in 2 arms: Chilia and Tulcea, and after about 17 km downstream the Tulcea arm devides  in two arms of Sulina and Sfantu Gheorghe. Between these three arms of the large delta exists, mostly,  the wonderful Danube Delta teritorry which is made out of a lot of sand banks (river sand banks Chilia Caraorman, Pardina, Stipoc, river-sea sand banks Letea, Sărăturile, Crasnicol etc.), small lakes (Sontea, Papadia, Litcov, Lopatna ), lakes ( Merhei, Mataita, Fortuna, Gorgova, Trei Ozere, Rosu, Rosulet, Puiu ) and swamps.
Danube Delta recorded in time, a slight entrance in the Black Sea, in the area around the mouths of the Danube flow, phenomenon captured by the fact that the old Sfantu Gheorghe light house is, currently, over 2 km from the shore of the Black Sea

The vegetation is abundant, comprising of reed and sedge, aquatic plants (especially water lilies). On the sand banks small forests of soft woods (poplar and willow). On the  larger sand banks (river-sea) forests of oak, mixed with fluffy ash, elm, poplar grow. On them runner plants are  abundant,  among which can be distinguished Periploca graeca and wild vine (Vitis silvestris), which can reach very large sizes.

The Danube Delta represents a big turistical attraction due to the fact that there is a wide variety of fish and ornithological fauna (domestic and pass). Here you can meet more than 300 species of birds (storks, ducks and wild geese, woodcock, cormorants, egrets, coot, heron, white and red califari, flamingo, swans, pelicans and white pelican, hawls, white eagles, etc..) some of them declared natural monuments and protected by law (pelican, red breasted goose / Branta ruficollis, which winter in the Danube Delta).

The Danube Delta, as a unit apart of the relief, can be noticed by a few characteristics

- the youngest  relief unit in Romania

- the most compact area of reed (c.240.000 ha)

- the most extensive sand dunes on Romanian territory (about 20,000 ha)

- the largest beach on the Romanian coast of the Black Sea (about 30 km long, 1-2 km wide)

- the largest lake in the country (Razim - 415 km 2)

- at highest hill river-sea (Letea - 17,000 ha)

- the lowest altitude in Romania (Sulina - 3.5 m)

- the most easterly city of Romania (Sulina )

- the richest and most varied fauna of Ornithology in Europe
