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 (the so-called 'Campinga' after the campsite there), stretching from the Sun Palace complex to the Riviera complex. The eastern end of the village's adjacent coastal line hosts the small port of local fishermen.

History:
The village of Sveti Vlas (St. Vlas) is believed to have been founded by the Thracian tribe of Larisi in the 2nd century BC. At that time, it reportedly bore the name of Larisa. It was renamed 'Sveti Vlas' in the 14th century AC after the patron saint of cattle growers and merchants.

During Ottoman rule (late 14th-19th century AC), the village appeared in administrative registrars as 'Manastir' ('Monastery') or 'Kyuchuk Manastir' after the five monasteries in the vicinity of the village. Unfortunately, none of the monasteries have been preserved. The village officially restored its name to Sveti Vlas after the reunification of the Bulgarian state in 1886.
