Primorsko is renowned for its graceful arcing ten-kilometer sandy beach, the longest and prettiest on the coast. The resort is a haven for youth and working Bulgarians who flock here in droves to avail themselves of the numerous trade union rest homes, hostels, student dorms and campgrounds.
While the center of Primorsko is the site of the International Youth Resort Center (Mezdunaroden Mladezhki Tsentur, or MMT) which annually attracted thousands of communist youth from around the world who, fittingly, camped out in huge communal tents. Nearby areas on the water are pleasant for walks, with memorable sights.
Primorsko is a youth town with a plethora 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). Here you can enjoy a fresh atmosphere and a never-ending party.
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.
