First recorded in the mid-14th century by Visconti, a traveller from Genoa, the remote seaside village of Sfântu Gheorghe retains an ever-so-slight alternative vibe, fed by the town's lovely, lonely beach and its sleepy, noncommercial core. It's also one of the best places in the delta to sample traditional cooking (including some fabulous fish soup).
The sleepy fishing port of Sulina is Romania's easternmost point and the highlight of any journey along the Danube's central arm. There's a beautiful, tranquil (during the day) beach here as well as a charming canal-side promenade. It's also an excellent base for forays deeper into the delta or on to the Black Sea.
