The River Wey Navigation and Godalming Navigation, geographically (but not historically) the Wey Navigation, form a continuous waterway which provides a 20-mile (32 km) navigable route from the River Thames between Weybridge and Hamm Court, Addlestone via Guildford to Godalming. The waterway is in Surrey and is owned by the National Trust. The Wey Navigation connects to the Basingstoke Canal at West Byfleet, and the Godalming Navigation part to the Wey and Arun Canal in the Broadford part of Shalford. The Navigations consist of man-made canal and adapted (dredged and straightened) parts of the River Wey.
