The Danube Delta is where Europe’s second-longest river reaches the Black Sea after 2,800 km, splitting into three arms and a maze of channels, lakes, reed beds, floating islands and oak forests on sand dunes. It is one of the largest wetlands in Europe and the best place on the continent to see pelicans, with more than 300 bird species recorded. Most of it lies in Romania and is protected as the Danube Delta Biosphere Reserve, a UNESCO World Heritage Site since 1991. There are almost no roads: you travel by ferry and small boat from Tulcea to fishing villages such as Crișan, Mila 23, Sulina and Sfântu Gheorghe, and you need a cheap access permit from the reserve administration. Come in May, June or September, bring mosquito repellent, and give it at least three days.

How the delta works: three arms and the villages
At Tulcea, the Danube divides. The Chilia arm in the north carries most of the water and forms the border with Ukraine. The middle Sulina arm was straightened in the 19th century into a shipping canal, 71 km long, that ends at the port of Sulina. The southern Sfântu Gheorghe arm winds in great loops to the village of the same name. Between them lie thousands of channels, shallow lakes and the largest continuous reed beds in the world, with floating reed islands (plaur), willow and poplar woods, and two ancient oak forests growing on sand dunes, Letea and Caraorman. The land keeps growing into the sea with the silt the river brings down.
About 10,000 people live in the reserve, many of them Lipovans, Old Believers whose ancestors left Russia in the 18th century, along with Romanians and Ukrainians. Most villages can be reached only by water.
- Tulcea: the gateway town on the Danube, with the ferry port, hotels, the ARBDD headquarters and the Danube Delta Eco-Tourism Centre (aquarium and exhibition).
- Crișan: a village strung along the Sulina arm, the most popular base for boat trips into the channels and lakes; it has an ARBDD visitor centre.
- Mila 23: a Lipovan fishing village on the old course of the Sulina arm, reached by boat, known for its fish dishes and its world-class canoeists.
- Sulina: Europe’s easternmost town, at “kilometre zero” of the Danube, with an old lighthouse museum, the 19th-century Maritime Cemetery, the old offices of the European Danube Commission, and a long sandy beach.
- Sfântu Gheorghe: a remote village where the southern arm meets the sea, with a wild beach, fish restaurants and, usually in August, the Anonimul film festival.
- Murighiol, Uzlina and Dunavățu: on the southern edge, reached by road from Tulcea, with hotels and boat trips to the lakes of the Sfântu Gheorghe arm.
- Chilia Veche and Periprava: quieter villages on the Chilia arm, near the Letea forest.
The ARBDD access permit (as of October 2026)
Everyone who visits the reserve for tourism, including on organised boat trips, needs a tourist access permit from the Danube Delta Biosphere Reserve Administration (ARBDD). Many hotels and tour operators include it or buy it for you; ask.
| Permit | Price | Notes |
|---|---|---|
| Tourist access, 1 day | 5 lei | Per person |
| Tourist access, 7 days | 15 lei | Per person |
| Tourist access, to the end of the year | 30 lei | Per person |
| Own boat on the channels, 7 days | 20 lei | Or 100 lei to the end of the year |
| Vehicle where road access is allowed, 1 day | 10 lei | Or 100 lei to the end of the year |
| Drone under 500 g | 50 lei | Separate photo, filming and drone permits apply |
The access permit is free for pupils and students, pensioners, people with disabilities, war veterans and residents of the reserve and neighbouring communes. You can buy it online on the ARBDD permit site (permise.ddbra.ro) by card; by SMS to the short number 7494 (text TUR1, TUR7 or TURAN followed by your name, for 1 day, 7 days or the year), which may work only from Romanian mobile networks; at the 24-hour permit machine at the ARBDD headquarters in Tulcea (Strada Portului 34A); or in cash at the ARBDD information centres in Crișan, Sulina, Chilia Veche and Murighiol. Carry it, on paper or on your phone: reserve rangers and the police check boats. Fishing needs a separate permit.
Boats: Navrom ferries, fast boats and small-boat tours
Navrom Delta, the state-subsidised operator, runs the regular passenger lines from Tulcea to Sulina, Sfântu Gheorghe and Periprava, stopping at villages on the way, plus services to Mila 23 and Caraorman. On its autumn and winter timetable, which started on 1 October 2026, boats leave Tulcea for Sulina at 13:30 on Mondays, Wednesdays, Thursdays, Fridays and Saturdays and return from Sulina at 07:00 on Mondays, Tuesdays, Thursdays, Fridays and Sundays; boats for Sfântu Gheorghe leave Tulcea at 13:30 on Mondays, Wednesdays and Fridays and return at 07:00 on Tuesdays, Thursdays and Sundays. In summer there are more sailings, including fast boats. Tickets can be booked on Navrom Delta’s website; children under 7 travel free and pensioners pay half. As a guide, press reports give the 2026 adult fare from Tulcea to Sulina as about 60 lei on the classic ship and about 70 lei on the faster boat. The classic ship takes about four hours to Sulina.
To explore the narrow channels and lakes, which the big boats cannot reach, you need a small boat with a local guide. Fishermen and guesthouses in Crișan, Mila 23, Murighiol and Sfântu Gheorghe offer trips of two to eight hours; rowing boats and canoes are the quietest way to approach birds. Agree the route, the length and the price in advance, and choose operators who respect the speed limits and keep their distance from colonies.
Birdwatching through the year
The delta lies on a major migration route, and the mix of habitats draws more than 300 species. Highlights include the great white pelican and the rarer Dalmatian pelican, pygmy cormorants, glossy ibises, spoonbills, herons and egrets of many kinds, white-tailed eagles and, in winter, flocks of red-breasted geese.
- April and May: the spring migration and the start of breeding; the best time for variety, with colonies busy and pelicans back from Africa.
- June to August: pelicans feeding on the lakes, young birds in the colonies, water lilies in bloom; early mornings are best before the heat.
- September and October: the autumn migration, with waders on the coast and huge flocks of pelicans gathering before they leave.
- December to February: wintering geese and ducks, especially around the lagoons in the south; cold, with few services open.
Bring binoculars, go out at dawn, and keep at least the distance your guide suggests from nesting colonies.

Mosquitoes, heat and other practicalities
Mosquitoes are part of life in the delta. They are worst from June to August, at dawn and dusk and near reeds and still water; on hot, windless evenings they can be fierce. Use a strong repellent, wear long, light-coloured sleeves and trousers in the evening, and choose a room with screens on the windows. Bring sun protection too: there is little shade on the water, and July and August days are often above 28 °C. In some villages there is no cash machine and card payments are not always possible, so take enough lei from Tulcea. Mobile coverage is good in the villages and patchy on remote channels.
Activities and best months
- Boat tripsNavrom Delta runs the passenger lines from Tulcea on all three arms of the Danube (Tulcea-Sulina, Tulcea-Sfântu Gheorghe, Tulcea-Periprava) and to Mila 23 and Caraorman, with online booking. ARBDD has approved tourist routes in the reserve, most of them by water, from Tulcea, Murighiol, Jurilovca, Chilia Veche, Crișan, Sulina and Sfântu Gheorghe (for example Tulcea - Mila 35 canal - Sireasa - Șontea - Olguța - old Danube - Mila 23 - Crișan - Maliuc - Tulcea); visitors need the ARBDD access permit.
Rules of the reserve
Large parts of the reserve are strictly protected and closed to visitors, and tourism is allowed on marked routes. Don’t land on islands or enter colonies; don’t throw rubbish in the water; camp only at authorised sites; keep noise down near birds; don’t pick water lilies; and fish only with a permit. Drones, photography for commercial use and filming need separate ARBDD permits. The Letea forest, with its wild horses, is visited only on authorised routes, usually by cart or on guided walks from C.A. Rosetti or Periprava.
Getting there and getting around
To Tulcea
From Bucharest, Tulcea is about 280 km, roughly 4 hours 30 minutes by car or by direct coach and minibus. From Constanța on the Black Sea it is about 2 hours. Trains to Tulcea are slow, with changes, so most visitors drive or take the bus. Buy a rovinieta before you drive on national roads. Tulcea’s small Danube Delta Airport has very few scheduled flights.
Into the delta
From Tulcea, take the Navrom ferry or a fast boat along the Sulina arm to Crișan or Sulina, or the Sfântu Gheorghe line; or drive to Murighiol, Uzlina and Dunavățu on the southern side. Many guesthouses meet guests at Tulcea or at the nearest pier with their own boat. Leave your car in a guarded car park in Tulcea or Murighiol.
When to go and how long to stay
The delta is the driest and sunniest part of Romania, with hot summers, mild autumns and cold, windy winters when the channels can freeze. The table uses the 1991–2020 climate normals of Romania’s National Meteorological Administration for Tulcea (at the edge of the delta) and Sulina (on the coast), from the World Meteorological Organization’s collection. Sulina gets only about 240 mm of rain a year and more than 2,300 hours of sunshine; Tulcea about 490 mm.
| Season | Average high, Tulcea | Average high, Sulina | Days with rain a month (Tulcea) | What it’s like |
|---|---|---|---|---|
| Spring (Mar–May) | 11 °C rising to 23 °C | 8 °C rising to 19 °C | 5–6 | Migration, nesting colonies; cool on the coast |
| Summer (Jun–Aug) | 28–30 °C | 24–27 °C | 4–6 | Hot and sunny; pelicans and water lilies; mosquitoes at their worst |
| Autumn (Sep–Nov) | 24 °C falling to 11 °C | 22 °C falling to 11 °C | 4–5 | Warm, settled September; autumn migration; fewer insects |
| Winter (Dec–Feb) | 4–6 °C | 4–6 °C | 5–6 | Cold, windy, sometimes frozen; wintering geese, few services |
Night-time lows in Tulcea average about −3 °C in January and 18 °C in July. Many guesthouses and boat operators open from about April to October; winter visits need planning.
