Sunny Beach is a major seaside resort on the Black Sea coast of Bulgaria, located approximately 35 km north of Burgas in Nessebar municipality, Burgas Province. It is the biggest and most popular holiday resort of the country, and is home to over 800 hotels with more than 300 000 beds. There are also 130 restaurants and numerous live music bars, pubs, nightclubs, discos, cafes. It has been undergoing continuous expansion for many years. In recent years almost the whole hotel base has been renovated and several new luxurious hotels have been built as well as many apartment complexes. It is widely believed in Bulgaria that Sunny Beach was heavily overdeveloped in the 2000s to the detriment of its greenery, former serenity, safety, and the quality of public services.
Sunny Beach has a very small permanent population, but during the summer the resort is home to many thousands of tourists. The main strip of high-rise hotels backing onto the beach is several kilometers long and extends along a wide bay between Sveti Vlas and Nessebar.
