De Muur is an easy shore dive on Grevelingen breakwaters.
De Muur is an easy shore dive in Lake Grevelingen built around four breakwaters with small beaches between them. The overgrown structure gives the site its shape, and the dive is best enjoyed as a slow search along the rockwork and sandbanks rather than a depth-driven route. It is a calm, beginner-friendly stop with plenty of small-life detail and limited parking.

Possible on the shallow breakwater ends, but the site is better treated as a relaxed shore dive than a freedive destination.

Snorkeling is possible on the shallow edges, but the small-life detail is better on a short dive or freedive.
