The beauty and the attractiveness of Sinemoretz have been determined by its unique natural features - a combination between sea, woods and river. It is an environmentally clean area, part of Strandja natural park.
The most valuable treasures of Sinemoretz are the beaches, preserved in their wild and untouched beauty. The village has five beaches around and three of them are at a very close distance.
The north beach is situated in a wide and open bay, and its sand sleeve is a kind of barrier between the sea and Veleka River. At one of its edges the picturesque creek of the river is curving.
The south beach, also called Butamyata has lifeguards and is the most visited one. It is maintained and clean; rent umbrellas and sea bikes are offered, in the small restaurants around one can find food, drinks and ice-cream. The beach itself has a broad sand line and is surrounded by woods.
The beach Linden Threes is situated south of the village and it is within 20 minutes walk from there. It is not so popular and is guarded by thick woods.
Listy is around 3,5 km south and could be reached only on foot.
Silistar is the last beach, the closest one to the Turkish border. It is situated 5,5 km south of Sinemoretz, and at its left edge Silistar River flows into the sea. The sand there is neighbouring the woods.
North of the village is the mouth of Veleka River - the cleanest river in Bulgaria. It springs in the Turkish part of Strandja Mountain and it's full of fish, around 30 different species are found. Along its coast are spread the so called "longosa woods" - they consist of exotic, thick vegetation that could be observed only along the rivers close to the Black Sea. Also some endangered of extinction species could be seen-pine tree, bamboo, yellow wild lilies, and others.
