Bulgarian Black Sea Coast forms the eastern edge of the country. It is full of relatively undiscovered resort towns, as well as large industrial port cities such as Burgas and Varna. Nesebar is a beautiuful small town a few hours south of Varna and is one of many UNESCO World Heritage sites in Bulgaria. Primorsko is a resort on a cape jutting out towards the Black Sea, mostly frequented by Eastern Europeans. If you're looking for a beach resort with notorious nightlife, head straight to Varna, especially during the summer season.
