Sliedrechtse Biesbosch

Sliedrechtse Biesbosch is a nature area in Dordrecht made up of interconnected waterways, islands, and wetlands. Willow forests, reed beds, and wet grasslands dominate the landscape and support hundreds of bird species throughout the year.

This wetland was created after a major flood in 1421 that devastated agricultural lands and left behind a water-soaked landscape. Over the centuries, water continued to shape and define the character of the region.

The area draws people who spend time watching birds and walking through nature, with locals and visitors often exploring the waterways by boat to experience the landscape directly. Place names here reflect earlier settlements and the long history of living alongside water.

The area has marked trails and observation points for visitors to explore on foot, with parking available at main entrances and information stations nearby. Visiting during spring and autumn offers the best experience, when paths are more accessible and bird activity is highest.

Tidal currents move through the area, creating a rare freshwater ecosystem where salt and fresh water meet and mix. This blend of conditions produces a landscape found in very few places in Europe.
