General information about La Slack Dunes

Right next to the Slack there is a protected dune area. This area has some high sand dunes and is currently under restoration. You can't enter this area yourself, but via a footpath between the Slack and the dune reserve on the one hand and the beach on the other, you can still take very nice pictures. You can compare the area somewhat with the Duinenreservaat "De Westhoek" of De Panne. Do not miss to visit the Vauban Fort.

Visitor tips for the La Slack dunes

General tips:
1) if you are looking for other nearby attractions, consult our Tourist map of Top.Vlaanderen.
2) You can consult our overview lists: by category ( e.g. timeline, size, ...) or by region
3) You can also always consult tourist services: see our overview of tourist services

Tip 1: Want to visit the Fort d'Ambleteuse visit then it is best to park your car in the village of Ambleteuse itself. The fort is located on the outskirts of the village. Please note that you cannot just go from the village to the dune reserve (and vice versa). The little river can be just too deep even at low tide and at high tide there is the danger that you cannot go back. Then you have to make a whole detour to get from one to the other.

Tip 2: If you want to visit the Dunes Reserve, you can use (if there are not too many people) one of the 2 parking lots belonging to this area. If you choose the North parking lot, you can reach the beach via two hiking trails next to the Slack. You will also pass an additional protected area where some protected bird species live. Obviously, you are not allowed to enter this area either. It is a small parking lot, so it fills up quickly. Being there on time (e.g. before 11 am) is recommended. Mobile homes cannot park there either (max. height is 2m 10), they have to go to the South parking lot.
