The youngest branch of the Danube Delta stretches for some 72 miles along the border with Ukraine and has the greatest flow of water (approximately 60%) of the three arms. Its shores are home to several scattered villages – Patlageanca, Ceatalchioi, Pardina, Tatanir – and Chilia Veche, a settlement with a long history (initially a Greek colony called Achillea).

Centuries ago, Chilia was a port on the Black Sea, a vital link between Europe and the Orient. In time, the alluvium deposited by the Danube has extended the land ever further into the Black Sea. Today, Chilia stands more than 25 miles from the sea. First documented in 1241 in the works of the Persian chronicler, Rashid al-Din, Chilia Veche was the site of a battle between the armies of Mahomed II, the conqueror of Constantinople, and forces led by Vlad Tepes (Vlad the Impaler). A town on the Ukrainian side of the Danube, known as Novo Kilia (Chilia Noua, or ‘Newer Chilia,’ in Romanian) was founded by Stephen the Great of Moldavia in the 15th century in order to counteract the Ottoman Empire.

Lake Rosca (Lacul Rosca), a strictly protected reserve located between Chilia Veche and Periprava, is home to Europe’s largest white pelican colony; the area also harbors geese, egrets and storks.

Periprava, downstream from Chilia Veche, is the last site served by passenger boats on the Chilia arm. South of Periprava, you can explore the impressive Letea Reserve (Padurea Letea) with trees more than 500 years old. Oak, black poplar, elm, ash and thorny shrubs are smothered in the tropical creeper named periploca, a Mediterranean plant with reddish-brown bark and simple, glossy leaves, giving the Letea Forest its tropical looks. Here, you may encounter black-bellied foxes, wild horses, boars, falcons and white-tailed eagles. The surrounding sand dunes are home to tortoises and lizards.

Note: Access to Letea Forest is permitted only with a guide (warden) on the designated route.

You can find accommodations in nearby Letea Village and spend a few days touring the surrounding waterways.
