THE LARGEST LAKE AND THE ONLY ROCKY ISLAND IN ROMANIA

Razelm Lake & Popina Island

The Local Legend of Razelm Lake

Lake Razelm, or Razim, is the largest lake in Romania, a freshwater liman located in the southern part of the Danube Delta, in Tulcea County, near the Black Sea coast. Before the 1980s and the subsequent communist embankments, the Razelm lagoon complex communicated with the Black Sea through the Periteașca and Portița mouths, allowing marine fish to access it for spawning. After closing these two mouths with dikes, the lagoon became a freshwater lake – fed by the Danube through the Sfântu Gheorghe branch and the channels branching south: Dranov and Dunavăț.

Lake Razelm

Lake Razelm is a spectacular and wild expanse of water, covering about 415 km² with a maximum depth of 2.80 meters. However, local legend has it that Lake Razelm is cursed. Over time, the stories of locals center around the enigma of those who, mysteriously, have never managed to return to shore once they went out on the lake. The curiosity of tourists to discover the beauty of Lake Razelm culminates with the distant visiting of Popina Island. This is a strictly protected area within the Danube Delta Biosphere Reserve, located in the northern part of Lake Razelm.

The Landscape & Fauna of Lake Razelm

The landscape of Lake Razelm will captivate you with its clear and warm water, clean air, and the presence of birds. The vegetation is typical of the Danube Delta and is rich in dense reed beds, white and yellow water lilies, willows, and aquatic species of bulrush and water thistles. Lake Razelm shelters a wide variety of common fish species, as well as freshwater fish – Cega (among the smallest sturgeons) and Viza (a species threatened with extinction in our country). In the thickets along the shores, you can spot otters (semi-aquatic carnivorous mammals with chestnut-red fur) and raccoon dogs (wild animals similar to dogs with valuable fur).

Razelm-Sinoe Complex

Also known as the freshwater sea, Lake Razelm is part of the Razelm-Sinoe Complex or Razim-Sinoie Complex, located south of the Danube Delta, over an area of 1,145 km². The complex is a component of the Danube Delta Biosphere Reserve and a Special Avifaunal Protection Area, alongside the Danube Delta. The Razelm-Sinoe Complex is composed of approximately 85% lagoon-type lakes (including Lake Razelm), limanic lakes, and lakes between sandbanks, spanning 863 km².

The Razelm-Sinoe Complex represents the only brackish coastal lakes in Romania. These are low-salinity lakes, resulting from the mixture of freshwater and saltwater, connected both to the Danube and the Black Sea. Currently, the Razim-Sinoie complex is divided into two units: the Razim unit with the lakes Razim, Golovița, Zmeica, and Babadag (Tauc and Topraichioi) – isolated from the sea, and the Sinoe unit with the lakes Sinoe, Nuntași, and Tuzla – connected to the sea via a sluice.
