The River Wharfe is a Yorkshire river originating within the Yorkshire Dales National Park at Beckermonds in Langstrothdale, where Greenfield Beck and Oughtershaw Beck meet at an elevation of around 310 metres. From there it flows approximately 60 miles (97 km) southeast through Wharfedale before joining the River Ouse near Cawood, south of York. For much of its middle course it forms the county boundary between West Yorkshire and North Yorkshire.

The upper reaches of the river, from the source down to around Addingham, run through a steep, troughlike valley and have a distinctly different character from the lower sections. The river passes through or near Kettlewell, Grassington, Bolton Abbey, Addingham, Ilkley, Burley-in-Wharfedale, Otley, Wetherby, and Tadcaster. A popular paddling stretch runs from Bolton Abbey downstream through Ilkley to Otley, a section recommended for experienced paddlers. Those planning trips on this stretch are advised to identify the locations of weirs in advance and to check river levels before setting out, as both represent significant safety considerations.

The river corridor offers opportunities to observe water-loving wildlife including herons, otters, and kingfishers. Notable features along the route include Linton Falls near Grassington, which also hosts one of two hydro-electric generating plants on the river. The surrounding landscape of Wharfedale draws considerable tourism, and the valley is well served by waymarked walking routes, which can be useful for shuttle logistics.

Kayaking and canoeing are established activities on the Wharfe, and the river is used by paddlers of varying experience levels, though the upper sections in particular demand appropriate skill given the steeper gradient and more technical nature of the water. The lower reaches through the Vale of York are considerably more gentle in character. Paddlers should be aware of weirs throughout the river's course and treat them as primary hazards requiring careful scouting or portaging.
