Near the town of Primorsko is the Ropotamo reserve. It extends on both sides of the eponymous river-Ropotamo. Ropotamo was declared for reserve in 1940 and It is composed of smaller reserves "Arcoutino" - marsh lagoon with Vegetable species, "Snake Island" famous with its cactuses and the snakes, "Sea Wormwood", the name of the herb, "Water Lilies," which includes lily garden in the old riverbed. Ropotamo is about 50 kilometers long, and is formed by the rivers and Tserovska and Rosenska which spring from Strandja. In its upper stream it is freshwater, but approaching the sea it becomes saltwater.

The landscape here is like a paradise - lush greenery on the coasts, which alternates with sand dunes, water is calm, sometimes forming lush meadows and bogs, overgrown with lianas, reeds and irises.

Here are kept more than 11 endangered plants and animal species listed in the Red Book of Bulgaria. It is established the habitat of 226 species. From here goes VIA PONTICA - the road of the migratory birds departing for warmer countries. In this natural area is found about 18% of the flora and fauna of Bulgaria.

All these natural treasures can be seen by boat. In 2003 there was opened a research center equipped with facilities for demonstrations and access to complete information about the area of the reserve. Around Ropotamo river are soaring many interesting rocks as the most popular among them is the Lion's head. It represents many rocks that form the image of a lion's head in profile. There are several legends about this rock, and one of them is that at the top of the rock is situated a well, in which is buried treasure, hidden from Valchan Chieftain. According to some archaeologists, the Golden Lion was the guardian of Tracian fortress Ranuli.

"Arkutino" keeps amazing populations of water lilies. There is located one of the cleanest beaches - boundary between the marsh and the sea and the bed of Ropotamo river is separated from high coastal dunes. The surface of the bog is covered with water lilies and between the reeds and bulrush sneak irises, swans and herons. In 1962, the marsh and the dense forest around it have been declared botanical reserve. The most characteristic feature of the reserve is the presence of lianas.

Beglik Tash is associated with the cult of the Mother Goddess and there were found gems that were offered as gifts to the goddess. Near the altar there is a stone throne of the ruler or priest. On the stones are carved holes which miss sunshine at the solstice that illuminate these points. Sunlight that falls from the main altar, divides the day of 6 equal parts.
It is believed that the construction of the shrine dates back to XIV. in before Christ and did not stop working until the V century It is believed that on the rock bed are gathered in ritual union of the High Priest and High Priestess, and baths which are found around the bed have served to fill with water cooking oil, wine and milk and thus unite all of the earthly powers.
