The Wolderwijd is a shallow bordering lake situated between the provinces of Flevoland and Gelderland in the Netherlands, created in 1963 during the reclamation of Southern Flevoland. It is one of four Veluwe bordering lakes and was designated a Ramsar wetland of international importance in 2000. The lake averages just 1.7 metres in depth, and the water remains waist-deep for hundreds of metres from shore, making it a notably flat and shallow body of water. It contains two islands, De Zegge and De Biezen. The nearby settlements of Harderwijk and Zeewolde sit on opposite banks, with Zeewolde and the municipality of Zeewolde occupying the northern and western shores (Province of Flevoland), and Harderwijk on the southern and eastern side (Province of Gelderland).

The Wolderwijd connects to adjacent lakes without sharp boundaries: to the west near Strand Horst it transitions into the Nuldernauw, and to the east at the aqueduct along provincial road N302 it becomes the Veluwemeer. This interconnected system means paddlers can extend trips into neighbouring waters.

Water quality is described as clean. Conditions are generally flat, with chop developing only in stronger winds. Wind is predominantly from the southwest through northwest, and can be gusty and variable — ranging from completely calm to very windy within the same month. The best months for wind-dependent activities are March through May and September through November, while July and August see the heaviest beach use by swimmers. Designated swim zones are marked by lines in the water, and these areas must be respected and avoided.

The beach at Zeewolde is sandy, with a soft sand area of approximately 40 by 200 metres available for launching. Facilities in the area include parking, a shop, showers, toilets, and food. The paddling season generally runs from March through the end of November. A wetsuit is typically not needed during summer months, while a shorty is recommended in spring and autumn, and a thicker suit in winter.
