The island of Saint Ivan is situated just 2km away from the old town in northern direction. It is the biggest Black Sea island in Bulgarian territorial waters and shelters a sonar lighthouse showing the way to Bourgas Bay. Once upon a time (6 centuries ago), the island hosted a monastery called The Holy Virgin which was later renamed into St. Ivan Prodromos (St. Ioan Precursor). You can get there by taking a boat from the port in The Old Town of Sozopol. In the sea off this island there is a unique underwater natural phenomenon known as the stone forest.
No further than 10 km to the south of Sozopol there are the nature reserves of Water Lilies and Ropotamo River. The conservation area of Kolokita is between Rayski Zaliv and Kavatsite Campsite. It features a fascinating combination of picturesque scenery, cliffs, fiords and marine aquavatoria.
