Ropotamo river springs from a place near to the village of Bosna (some 50 kilometers to the west in the Strandzha Mountains). The mouth of the Ropotamo river is situated in the middle of the coast line stretching between the holiday city of Duni and the town of Primorsko, about 45km to the south of Bourgas.
The most distinguishing feature of the river is that it is salt. In its beginning it is freshwater, but after a few kilometers it becomes salt. The only place where there was fresh water was the “King well” near to the riverside of Ropotamo.
The river has a rich and unique variety of flora and fauna. The Ropotamo river is particularly famous for its tender water lilies. A boat trip down the river or a walk along its banks is an unforgettable experience. The tourists are delight from every tortoise, at every heron, sneak and bird. There are 3 species of tortoises in the river and some of those species grew to 35 cm.
The waters of the river are brown, the water looks dirty, but it is not, and this is because the red plankton reproduced here. In the region of the Ropotamo river the fishing and the hunting are forbidden.
