The Danube–Black Sea Canal is a navigable canal that connects the Danube River to the Black Sea.  The canal, administered from Agigea, plays a crucial role in linking the North Sea and the Black Sea via the Rhine-Main-Danube Canal. 

The main branch of the canal stretches 64.4 kilometers and connects the Port of Cernavodă with the Port of Constanța.  The northern branch, known as the Poarta Albă-Midia Năvodari Canal, covers 31.2 kilometers and links Poarta Albă to the Port of Midia. While the canal itself isn't a major tourist destination, several interesting sights can be found nearby.  The Central Eco-Tourism Museum of the Danube Delta allows visitors to learn about the delta's diverse plant and animal life.  History buffs can explore Romania's oldest town, Histria Archaeological Complex & Museum, founded by Greek traders.  Constanța offers a variety of historical and cultural attractions, including the National History & Archaeological Museum, the Roman Mosaic, and the Great Mahmudiye Mosque.
