Grevelingenmeer is the largest saltwater lake in the Netherlands, formed from one of the four former estuaries in Zeeland, the most southwestern province of the country. Its saltwater character produces notably clear water compared to many Dutch inland waters, which has made it a popular destination for both divers and paddlers. The lake is dotted with a number of islands, which adds variety and navigational interest to paddling routes.

One well-established paddling route involves circumnavigating Hompelvoet island, launching from Ouddorp harbor on the north shore of the lake. The harbor offers a practical put-in point, and a small restaurant at the end of the dike provides restroom access. The route around Hompelvoet includes the option of a lunch stop at a small archipelago on the south side of the island. Landing on Hompelvoet itself is not permitted, as it is a protected bird area.

Wind is a significant factor on the Grevelingenmeer. The lake's open, exposed character means conditions can build quickly, and paddlers should be prepared for substantial wind and chop. The saltwater environment also means that spray and wind-driven water can leave a noticeable salt residue on skin and gear after a day on the water.

The lake sits on the border of Zuid-Holland and Zeeland, on the island of Goeree-Overflakkee, and is roughly 45 minutes by road from Rotterdam. The surrounding area offers cycling and walking routes, and camping facilities with boat launch access are available nearby, including at Camping de Grevelingen near Nieuwe Tonge on the southern shore. There are plans to construct 13 new islands on the inside of Brouwersdam as a vacation development, which may alter the character of that area of the lake in the future.

The combination of saltwater clarity, island geography, and open-water exposure makes Grevelingenmeer a destination suited to paddlers comfortable with big water and variable wind conditions rather than those seeking sheltered flatwater paddling.
