The old town of Nesebar has been declared a World Heritage Site by UNESCO. It's on the coast of the Bulgarian Black Sea. It's well worth a visit, but in summer, it gets very crowded because many people come daily to the beaches and to discover the new city of Nesebar, as well as other places nearby. Nesebar has a rich historical and architectural legacy, and like many other places in the Balkan region, it reminds us of a crossroads between old empires. Besides the old monuments of its rich historical past, it has a nice beach and a picturesque seaport.
Sozopol is one of the mythical enclaves in the Black Sea, Bulgaria. It's 30km approx from Burgas. Sozopol has two parts, the old town and the new town. The old city is the hub of the past, with its old houses and cobblestone streets that serve as a lookout to the sea. Unfortunately there's a lot of tourism here in summer, especially in the new part. In the old part of town there is the fishing port with its little blue boats and you can swim in some designated areas.
Chernomorets is undoubtedly the best place I've visited in the Black Sea, Bulgaria. Places like Sozopol and Nessebar are beautiful, with their old towns and thousands of visitors, but Chernomorets has a special something. Maybe it's just me that felt relaxed and calm here compared to the bustle of the other tourist villages. Chernomorets has a nice beach and beautiful surroundings full of small cliffs and breakers. To get there it's easy by public transport, there is a bus that passes through on its route from Burgas-Sozopol.
