De Zandkreek is a key access point on the eastern end of the Veerse Meer, where the Zandkreekdam separates this brackish lagoon from the Oosterschelde.

The dam, part of the Delta Works, connects the islands of Noord- and Zuid-Beveland and was completed in 1960.

A navigation lock — the Zandkreeksluis — built into the dam allows vessels to pass between the Oosterschelde and the Veerse Meer, providing onward connections toward Middelburg and Vlissingen via the Walcheren navigation channel.

For recreational boaters, the Zandkreeksluis is one of only two primary access points to the Veerse Meer, making it an important waypoint on this popular cruising ground.

The lock has been subject to periodic closures for renovation work, so skippers should check current schedules before planning a passage.

When the lock is closed, the alternative route via the Kanaal door Walcheren adds a considerable detour, particularly for those approaching from the north.
