Danube Delta Guide: Everything You Need to Know Before You Come
The Danube Delta is the largest wetland in Europe and the second most biodiverse in the world after the Amazon -- recognised by UNESCO as a Biosphere Reserve since 1991. It spans nearly 4,200 km² between Romania and Ukraine, where the Danube, after a 2,860 km journey through ten countries, flows into the Black Sea through three main branches: Chilia, Sulina and Sfantu Gheorghe. This is the general guide for anyone who wants to understand the place before visiting -- geography, nature, access and what makes the Delta different from anywhere else in Romania.
A biosphere reserve, not just a tourist destination
The UNESCO Biosphere Reserve status is not just a label -- it means large areas of the Delta are strictly protected, with limited access, and the activities allowed there (fishing, tourism, transport) are regulated by the Danube Delta Biosphere Reserve Authority (ARBDD). In practice, any serious visitor encounters this authority in one way or another: through the fishing permit on public waters, or through the access rules in strictly protected zones.
Geography and branches: Chilia, Sulina, Sfantu Gheorghe
The Danube splits into three main branches before the Black Sea. Chilia, the northernmost and youngest, carries the most flow and forms the border with Ukraine. Sulina, in the middle, is the only one navigable by sea-going vessels and has the shortest direct route to the sea. Sfantu Gheorghe, the southernmost, is the most winding and passes through some of the Delta's wildest areas. Holbina Trei Bibani sits in this southern part, near Dunavatul de Jos and Lake Razim, reachable only by boat through the channels between the branches.
Biodiversity: 300+ bird species, hundreds of fish species
The Delta is home to more than 300 bird species (many protected, such as the great white and Dalmatian pelican), dozens of freshwater fish species and a mosaic of ecosystems -- reed beds, willow forests, sand dunes, lakes and channels. For anglers, this abundance means healthy populations of pike, catfish, pikeperch and perch; for nature lovers, it means one of the best birdwatching destinations in Europe.

How to get around in the Delta
There are no roads inside the Delta -- beyond the towns at its edge (Tulcea, Murighiol, Dunavatul de Jos), travel is exclusively by boat. That means every visit starts with a transfer on water, and the pace of the place is set by the channels, not by roads. At Holbina, the transfer from Dunavatul de Jos takes about 45 minutes and is included in the accommodation and fishing packages.
How to get to Holbina Trei Bibani →When to come, depending on what you're after
The Delta changes radically from one season to the next: spring brings migratory birds, summer is the classic holiday season, autumn is best for predator fishing, and in winter the Delta is nearly empty but spectacular, with tens of thousands of geese wintering here.
The complete season-by-season calendar →Fishing in the Delta: public waters vs. private lakes
On the Delta's natural waters, recreational fishing requires an ARBDD permit and follows the closed seasons set each year. Holbina offers an alternative: four private lakes, where fishing for pike, catfish and perch goes on all year, with no permit and no closed season -- because the fish are raised on site, not taken from the state fishery.
Fishing rules and permits in the Danube Delta →The authentic Delta vs. the tourist Delta
Part of the Delta -- especially the day-trip cruise routes from Tulcea -- is organised for mass tourism, with fixed schedules and large boats. Another part, harder to reach, remains almost unchanged: small villages, quiet channels, no tourist-boat traffic. Holbina, reachable only by private boat through less-travelled channels, belongs to this second category -- which is why guests talk about quiet and wild nature, not crowds.

What is the Danube Delta and why is it special?
The Danube Delta is the largest wetland in Europe, a UNESCO Biosphere Reserve since 1991, with more than 300 bird species and biodiversity rivalled globally only by the Amazon. It forms where the Danube flows into the Black Sea through three branches: Chilia, Sulina and Sfantu Gheorghe.
How do I get to the Danube Delta if I've never been there?
The simplest way: drive or fly to Tulcea or Murighiol, then continue by boat -- there are no roads inside the Delta. At Holbina, we organise the transfer from Dunavatul de Jos with the resort's own boat.
Do I need a guide to visit the Danube Delta?
Not everywhere, but it is recommended for strictly protected areas and for fishing -- local guides know the channels, the ARBDD rules, and where to find the best conditions depending on the season.
What is the difference between the Danube Delta and an ordinary guesthouse by the water?
The Danube Delta is a vast nature reserve with several branches, villages and protected areas -- it is not a single place, but an entire region. A guesthouse 'by the water' may sit at the Delta's edge without offering real access inside it. Holbina is inside the Delta, reachable only by boat.
Can you fish anywhere in the Danube Delta?
No. On natural waters you need an ARBDD permit and must observe the closed seasons. There are also strictly protected zones where access is banned or limited. Private lakes, like the ones at Holbina, operate under different rules -- no ARBDD permit and no closed season.
