Visit St Ivan Island
Less than a kilometre off of Sozopol’s coastline is St Ivan Island, the largest island in the Bulgarian Black Sea. Although it’s just a quarter of a mile wide, it’s got a history packed with ancient invasions, pirate legends and war stories – some dating back to the 4th century BC. Today, the island’s mainly a nature reserve, home to over 70 different species of birds, which nest on the rocks. You can catch a boat over from Sozopol’s harbour to explore this small-but-mighty isle for yourself.
