The Veerse Meer is a large area of non-tidal water, cut off from the sea by the delta barrage that protects the low-lying part of south Holland from flooding. The enormous lake, the former Schelde Estuary, is a paradise for yachtsmen, and Veere is one of the most popular small towns. All vessels arriving from the sea must first pass through the tidal barrage via the Roompotsluis lock. Once in the Oosterschelde, yachts turn right and enter the Veerse Meer through the Zandkreek lock. Veere is also accessible via the Walcheren Canal from Vlissingen, which is one of the easiest ways to enter the Dutch inland waterway system.
