Grasbroek is a sheltered freshwater shore dive with a marked route.
Grasbroek is a sheltered freshwater shore dive in Bornerbroek, built around a marked line route that links the pier, the Arcadis underwater house, and other objects. Parking sits close to the water, the entry is shallow, and the site works best as a calm repeat-training lake where modest visibility and no current keep the plan simple.

Depth range, seasonality, and planning context.
Reported Depth
0m - 12m
Depth Note
The entry zone is shallow, then the bottom slopes away through the marked route to the deep end around 11-12 m.
Best Season
Year-round; quieter off-peak periods are usually the easiest.
Typical Conditions
Shallow freshwater with a guided route, little to no current, and visibility that commonly sits in the low meters.
Hazards, restrictions, and access requirements.
Key Hazards
Safety Notes
Do not jump from the steiger. Watch for fishing lines, keep close in low visibility, and expect a colder layer below the shallow zone.
Access Restrictions
Diving is managed on site and requires check-in or prior booking with the camping operator; a small entry fee is charged.
Legal Notes
Treat it as managed private recreational ground: follow reception instructions, pay the site fee, and avoid entering when the waterfront is busy with other users.
Community notes to help plan your visit.
Scuba Diving
Best for relaxed shore dives, navigation practice, and object/line-following around the Arcadis route. Bring a light and keep the team tight when the water turns cloudy.
Freediving
Only suitable for controlled shallow practice if you already know the site. Visibility is modest and the marked route is better suited to scuba than casual freediving.
Snorkeling
You can explore the shallow edge, but the low visibility and managed route make it a short, limited snorkel rather than a full scenic swim.
