The Sveti Vlas (St.Vlas) village has about 3,000 inhabitants and is situated just 4 km to the north of Sunny Beach resort and 9 km away from the town of Nessebar. It lies in the skirts of the Stara Planina mountain (also called the Balkan mountain) and thus offers a beautiful combination of sea and mountain climate, considered favourable for those suffering from lung diseases. The adjacent beaches are of a total length of about 1km and average width of 16 metres.

Besides the village's central beach, there is also a smaller one - from the Sun Palace complex to the Riviera complex. The eastern end coastal line hosts the small port of local fishermen.
