- Danube Delta-kaleidoscope of original landscapes, the paradise of rush bushes, of numerous fishes, the Danube Delta is a region of great touristic beauty and has a real scientific value. It has 5,050 square km (out of which 4,340 square km on the Romanian territory, the rest on Ukrainian territory), its average altitude is 31 cm, great part of the region being under water. Varied images appear in front of the visitor: sand banks, large ponds, numerous rush bushes, sand dunes, forests, canals shadowed by old willows. All these and a permanent metamorphosis, a permanent modification of the Delta's forms and dimensions amaze the Romanian and foreign tourists every year. First mention of the Danube Delta was made by the Greek historian Herodotus who described the moment when Persian fleet of Darius entered the Delta, after a stop in Histria (515-513 B.C.). On this occasion Herodotus mentions that the Danube is divided into five branches before flowing into the Black Sea. The Danube Delta is considered the region "with the largest and thickest rush surface of the globe" (the numerous rush bushes preserve the natural balance); with the richest ornithological fauna of the world (more than 300 species); the youngest land in Europe (each year the land advances 40 m into the water); the largest sand dunes in Romania; the lowest level of mist in Romania; the lowest altitude of a town (Sulina-3.5 m); the shortest winter in the country (20 days with 00C). Due to its special morphological and hydrographical characteristics and to the originality of its flora and fauna, there have been established several complex natural preserves within this region: Letea Forest, Caraorman Forest, Rosca-Buhaiova-Hrecisca-Letea Saint George-Perisor-Zatoane, Periteasa-Leahova-Gura Portitei. In August 1990 UNESCO included the Danube Delta, this "immense geologic and biologic laboratory" where everything undergoes changes, in the biosphere reserves due to its scientific and landscape value. Its fauna is very diverse, there is no similar place in Europe, it has species that are unique in the world. There can be remembered the following birds among the 300 species: pelicans, geese and ducks, storks, cormorants, egrets, flamingo, swans, most of them are declared monuments of nature protected by law. It should be mentioned that Delta's sky is crossed by six ways of the migratory birds, it is situated at halfway between Equator and North Pole (parallel 450) so it is often a stop for the migratory birds. Many of the Delta's fishes have economic value: sturgeon, stor sturgeon, sterlet-important for the caviar. There can be remembered the following mammals: hermine, wild cat, muskrat, raccoon dog, and tortoise. The unrivalled flora comprises, among other species: white and yellow water lilies, bulrush, bracken, different kinds of reeds, water iris. Besides this immensely rich floral landscape, there are 8,000 ha of forests with giant trees on whose trunks grow climbing plants like lianas. Charmed by everything, the tourists do not know what to admire fist of all: the rush waving when the wind is blowing, the variety of birds and vegetation or the fishermen's villages spread along the channels. Non of the nature's lovers will forget the days spent fishing or in the fishermen's cabins or in a tent, the soup made by fishermen that cannot be cooked like this anywhere else.
