Primorsko  is a town and seaside resort in southeastern Bulgaria, part of Burgas Province. A well-known resort on the Bulgarian Black Sea Coast, it is located on a gore 52 km south of Burgas and has a beach strip of about 1 km². The average temperature is 27°C in July, often reaching 30-33°C and making Primorsko a favourable place for tourism.

Under communism, Primorsko was the site of the Georgi Dimitrov International Youth Resort Center (Mezdunaroden Mladezhki Tsentur, or MMC) which annually attracted thousands of communist youth from around the world who, fittingly, camped out in huge communal tents. While the centre of Primorsko is an overbuilt urbanlike sprawl, the MMC and nearby areas on the water are pleasant. If you happen to find cemeteries picturesque, there is an especially peaceful plot perched on the top of the bluff overlooking Primosko's beach. The rivers Ropotamo and Dyavolska reka run close to the town, and the Snake Island reserve is also nearby.

There are plenty of outdoor cafes, discos that thump around the clock, and inexpensive eateries such as the beachside Delfin Snack Bar (try the tasty midi pane [breaded deep fried mussels]). For the intrepid traveler curious to see how the current generation of Bulgarian youth is embracing capitalist excess, Primorsko is where it's happening. But if it's peace and quiet you're after, better look elsewhere.
