Grasbroek

Grasbroek, located in the Netherlands, is a well-known dive site popular among divers of all skill levels. This dive site features a line that extends from the corner of the pier, leading to the underwater house Arcadis. Above the house, there is a 5-meter platform, offering a unique diving experience. Exploring the mainline further reveals several other lines that branch out to different underwater objects.

Diving at Grasbroek allows divers to encounter a variety of aquatic life, ranging from common to rare species. During your dive, you may come across gobies, perch (Perca fluviatilis), crayfish, pike (Esox lucius), pikeperch (Sander lucioperca), and if you're lucky, even the elusive sturgeon.

One of the highlights of Grasbroek is its accessibility and suitability for casual divers. As you explore the dive site, you'll often find pikes hiding among the reeds or underwater growth at shallower depths. The sandy areas, free from plant growth, are home to a vibrant population of gobies and freshwater clams. Don't miss the black gobies that tend to hide in crevices around the objects. If you choose to dive at night, you may be accompanied by hunting perch, adding to the excitement of your underwater adventure.

While exploring Grasbroek, it's important to be aware of your surroundings. If you venture towards the left (east), keep an eye out for fishing lines laid by fishermen. However, it's worth noting that fishing is not permitted towards the west, making it an excellent alternative dive route beyond the pipes.
