The Danube Delta is comprised of an intricate network of waterways and lakes divided between the three main estuary channels of the Danube. This area of floating reed islands, forests, pastures and sand dunes covers 3,000 square miles and is home to a fascinating mix of cultures and people as well as a vast array of wildlife. Located at the tip of the three channels, Tulcea makes a great starting point for exploring the Danube Delta.

The Danube Delta Biosphere Reserve has the third largest biodiversity in the world (over 5,500 flora and fauna species), exceeded only by the Great Barrier Reef in Australia and the Galapagos Archipelago in Ecuador. Moreover, it is home to over 60% of the world's population of pygmy cormorants (phalacrocorax pygmeus), 50% of red-breasted geese (branta ruficollis) and the largest number of white pelicans (pelecanus onocrotalus) and Dalmatian pelicans (pelecanus crispus) in Europe.

A bird-watchers' paradise, the Danube Delta offers the opportunity to spot more than 300 species of migratory and resident birds, including eagles, egrets, vultures, geese, cranes, ibises, cormorants, swans and pelicans. Located on the 45th parallel, the Danube Delta makes for a perfect stopping-off point between the Equator and the North Pole for millions of migratory birds.

The Delta can be explored as part of a Danube River Cruise, or on day trips and boat excursions from Tulcea which has good hotels, restaurants specializing in fish dishes and the Museum of the Danube Delta.
