A nature reserve with a rare wealth of fauna and flora unequaled in Belgium, except in the Zwin nature reserve. The freshwater of the Yser, the only river in Belgium that flows directly into the North Sea, mixes with the salty seawater. Tidal action has created a unique mudflat and salt marsh area, an ideal breeding ground for a rich variety of benthic organisms such as worms, snails, seaweed, shells, and crustaceans. The constant interaction between salt and freshwater in the Yser estuary also creates a unique biotope, characterized by salt-tolerant plants such as samphire, sea plantain, and sea aster.

This nature reserve has a unique fauna and flora due to the mixing of the salty seawater and the fresh water of the IJzer River, which flows into the sea here.

Welcome to De Hoge Blekker, with its 33 meters the highest dune in the entire Flemish coastal region. A striking appearance and an impressive eye-catcher. The dune used to be a fixed navigation point for sailors. From a distance they could see the white back as a kind of 'flash' ('bleach' is the local dialect for 'flash'). The Hoge Blekker is a drifting dune that has covered some distances over time. The dune now covers an area of approximately 33 hectares. Enough room for a picnic stop!

Beautiful semi-paved walking path that goes through De Doornpanne. Every season is colored differently here. With a bit of luck, donkeys or ponies will come to greet you.
