The park was created by a catastrophic flood in 1421, which submerged 17 villages and turned fertile polders into an inland sea.
Biesbosch means 'sedge forest' in Dutch, referring to the dense vegetation that flourished after the flooding.
It is one of the few places in the Netherlands with a noticeable tidal range of approximately 20 to 30 centimeters.
The Eurasian beaver population here is the largest in the Netherlands, with over 100 established lodges.
The park functions as a natural water filter, cleaning sediment from the rivers Meuse and Waal before it reaches the sea.
White-tailed eagles, the largest raptors in Europe, have successfully established breeding territories within the park's dense woods.
During the Second World War, the area was used by the 'Line-crossers' to transport intelligence and refugees through the flooded marshes.
The park's willow plantations were historically harvested for 'griendhout,' a type of wood used in basket weaving and dike reinforcement.
Nationaal Park De Biesbosch is one of the largest freshwater tidal wetlands in Europe, formed following the St. Elizabeth flood in 1421. The park features a complex network of rivers, creeks, and willow forests that are subject to constant tidal changes. It serves as a critical habitat for the Eurasian beaver, which was successfully reintroduced in 1988. The landscape is characterized by its dynamic water levels and interconnected islands, accessible primarily by boat or canoe. The region contains significant remnants of historical dike systems and polder landscapes. It is a vital stopover for migratory birds, including white-tailed eagles that now nest in the area. Visitors can navigate the park through numerous marked water routes or walking trails across the floodplains. The park provides specialized visitor centers that explain the hydraulic engineering and ecological history of the delta.

Rent a whisper boat or canoe to access the narrow 'kreken' (creeks) where motorized traffic is prohibited.
Bring binoculars, as the dense reed beds and high trees are home to rare bird species that are difficult to spot with the naked eye.
Always check the weather forecast, as open water routes can become challenging during high winds.
Avoid entering the water near shipping lanes; do not feed wildlife as it alters their natural foraging behavior.
Visitor centers may have reduced staff presence during winter months; some secondary trails may be inaccessible during extreme high water levels.
Stay on marked trails to protect bird nesting grounds; keep noise levels low to avoid disturbing beavers.
