Durrës is where most of the ferries from Italy arrive and where Tirana goes to the beach on a Sunday. It is a real city, with a port, traffic and apartment blocks, and a genuinely long sandy beach that shelves gently into shallow water.
Manage your expectations and it is fine. Do not come expecting the turquoise coves of the south. Come for a soft sandy beach an hour from the capital, the Roman amphitheatre in the middle of town, and cheap seafood on the promenade.
Durrës vs the Riviera
The Adriatic coast around Durrës is sandy and shallow with a brownish tint from the rivers. The Ionian coast from Vlorë south is rocky, clear and blue. If beaches are the point of your trip, keep going south.
Ferries
Overnight ferries connect Durrës with Bari and Ancona. The port is walking distance from the old town, and Tirana is under an hour by bus, which makes Durrës a sensible first or last stop if you are arriving from Italy.
