Danube Delta
The Danube Delta: Europe’s Largest and Least Touristed Wetland
Roughly 14,000 pairs of Great White Pelicans breed in the Danube Delta each spring, the largest colony in Europe by a substantial margin. Another 450 to 500 pairs of the rarer Dalmatian Pelican nest here too, a species listed as vulnerable globally. On a still morning in May, the pelicans rise from the reed islands in synchronized spirals, riding thermals over the lagoons in formations that look planned rather than accidental. This is the image most birdwatchers are chasing when they make the journey to Romania’s Black Sea coast. But the delta holds enough wildlife and enough silence to satisfy visitors who have no particular interest in birds at all.
The delta covers 5,800 square kilometres and sits at the junction of two major migratory flyways: the Black Sea coast route and the Balkans inland route. It records over 360 bird species, of which around 170 breed within the delta itself, representing approximately 98% of Europe’s aquatic bird fauna concentrated in a single landscape. A well-planned week can produce a species list above 150 without effort. Beyond birds, the Letea Forest within the delta harbors Romania’s only population of semi-feral horses, descendants of domestic animals abandoned over generations. No other delta ecosystem in Europe has wild horses alongside pelican colonies and white-tailed eagles, which makes the Danube Delta a genuinely unusual destination even by the standards of European nature tourism.
Getting There
The gateway city is Tulcea, on the Danube roughly 70 kilometres inland from the Black Sea. Most visitors fly to Bucharest (Henri Coanda Airport) and travel to Tulcea by train (approximately 3 to 4 hours, with several daily departures) or by car (about 3 hours on the A2 motorway and then national roads). From Tulcea, all access into the delta is by water. There are no roads connecting Sulina, Mila 23, or Sfantu Gheorghe to the outside world; the boat is not a romantic option but the only option.
Regular passenger ferry services (navrom) operate from Tulcea port to the main channels at modest prices, typically a few hundred Romanian lei for a round trip. Journey times vary: Sulina via the main Sulina arm takes around 3 to 4 hours on the slow ferry. Private speedboat hire from Tulcea runs approximately 275 lei per person (300 lei on weekends) with a minimum group size, and covers far more ground in less time. Organised day tours from Tulcea to Mila 23 with a traditional fish meal included start around 200 lei per person.
Where to Go in the Delta
Sulina
At the western end of the Sulina Channel, Sulina is the easternmost town in Romania and the entry point to the Black Sea. It has a particular melancholy to it: a lighthouse, a crumbling 19th-century European quarter from the time of the Danube Commission (a multinational body that managed the river’s commercial traffic), and a mixed cemetery where Greek, Romanian, Ottoman, and English merchant sailors are buried side by side. For a small town at the edge of Europe, Sulina’s history is unexpectedly international.
Mila 23
Accessible only by boat, Mila 23 is a Ukrainian-descended fishing community (the Lipovan Russians, Old Believers who fled religious persecution in the 18th century) living on a spit of land between channels. Life here runs at the pace of the water. The guesthouses are family-run, typically 7 to 8 rooms, with full-board packages that include meals and boat excursions into the reed beds. Casa Alexandru, Paradise Delta House, and Casa Vaida are among the well-rated small guesthouses here. Prices run around 50 euros per person per night with meals included, which represents exceptional value given the quality of the food (fresh carp, catfish, and pike prepared in the local saramura style, a simple broth with vinegar and herbs) and the remoteness of the location.
Sfantu Gheorghe
The southernmost of the three arms of the Danube reaches the Black Sea at Sfantu Gheorghe. This small village sits at the junction of river and sea, with a wild beach extending several kilometres in each direction, backed by dunes and without any commercial development. Green Village is the main four-star facility here. Casa Roko, renovated in 2025, is a smaller three-star option in the village centre. Sfantu Gheorghe is preferred by visitors who want the delta experience combined with swimming in the Black Sea.
Letea Forest
One of Europe’s oldest surviving native forests, Letea contains enormous old-growth oaks and the semi-feral horses for which it is known. Access requires a guide and prior arrangement, as the forest is a strictly protected zone. The horses are present but not guaranteed on any given visit; early morning and late afternoon give the best chance.
Birdwatching
May and June are the peak months. Breeding activity is at maximum, the pelican colonies are fully established, and species like the Eurasian Spoonbill, Glossy Ibis, White-tailed Eagle, and numerous warblers and herons are all present and active. A dawn boat trip through the reed channels in May is one of the more extraordinary wildlife experiences available in Europe at any price.
September and October offer a different experience: the breeding season is over but autumn migration brings waders and raptors passing through on their way south. The light in October over the lagoons is exceptional for photography.
The key birdwatching areas are Rosca-Buhaiova, the Uzlina and Gorgova lakes, and the channels around Mila 23. All require boat access.
Practical Notes
When to visit: April through June for breeding wildlife and spring migration. September through October for autumn migration and cooler temperatures. July and August are hot, humid, and heavily visited by Romanian summer tourists (primarily in Sfantu Gheorghe for the beach). Insect repellent is non-negotiable between May and September.
Booking ahead: The family guesthouses in Mila 23 and Sfantu Gheorghe have limited capacity. In May and June, rooms book out weeks in advance. Contact guesthouses directly or through Romanian tour operators rather than relying on generic booking platforms, which do not consistently cover these properties.
Equipment: Binoculars are worthwhile even if you are not a committed birdwatcher. Waterproof clothing is advisable from September through April. Sun protection is essential in summer; the reed beds offer no shade.
Food: The local diet in the delta is built around freshwater fish: carp, catfish, pike, and bream. Saramura (fish cooked in a vinegar and herb broth and served with polenta) is the regional staple and is prepared differently by each family. Caviar from wild carp is occasionally available from local fishermen. Avoid any offer of Danube sturgeon: the species is critically endangered and all commercial fishing and sale of sturgeon in Romania is illegal.
Respect for the ecosystem: The delta is a biosphere reserve. Do not stand in reed beds, do not approach nesting colonies at close range, and follow your boat guide’s direction on where it is and is not appropriate to go. The delta’s ecological integrity is exactly what makes it worth visiting; the pressures from tourism and upstream agriculture are already significant.
