About Sozopol

Sozopol's old town crowds onto a small peninsula, its wooden Black Sea houses and churches linked by lanes above the water. The beaches at Harmani and the resort strips to the north handle summer swimming, while the Apollonia festival brings arts to the town each September. June and early July offer warm water before the peak; September is quiet and warm, and winter closes most seasonal businesses but leaves the old streets to locals.
