The River Wey Navigation and Godalming Navigation together provide a 20-mile (32 km) continuous navigable route from the River Thames near Weybridge via Guildford to Godalming (commonly called the Wey Navigation). Both waterways are in Surrey and are owned by the National Trust. The River Wey Navigation connects to the Basingstoke Canal at West Byfleet, and the Godalming Navigation to the Wey and Arun Canal near Shalford. The Navigations consist of both man-made canal cuts and adapted (dredged and straightened) parts of the River Wey.
