The River Nidd flows through North Yorkshire, originating in the hills near Pateley Bridge and eventually joining the River Ouse. The river passes through the Nidderdale Area of Outstanding Natural Beauty, covering approximately 68 kilometres of paddleable water. The character of the river changes considerably along its length, making it suitable for a range of paddler abilities.

The upper sections near Pateley Bridge offer calm, gentle water well suited to beginners or those seeking a relaxed outing. The lower reaches from Hampsthwaite to Knaresborough are a commonly paddled stretch, where the river picks up pace and presents small rapids and obstacles appropriate for intermediate paddlers. Paddling through Knaresborough is particularly notable for the dramatic backdrop of the town's historic castle and cliffs. Further downstream, the river settles into calmer water as it approaches the York area.

A section of particular interest is the Nidd Gorge, located between Scotton and Bilton near the head of the gorge, which has been described as a mellow but scenic stretch. The Goldsborough to Kirk Hammerton section near Harrogate is another documented route. Weirs are present at various points along the river — some historic mill weirs, others more modern flood management structures — and paddlers should identify their locations and assess conditions before setting out. Water levels on the river can rise and fall quickly without warning, and the water can be cold.

The river corridor supports water-loving wildlife including herons, otters, and kingfishers. The surrounding landscape includes woodlands and farmland throughout much of the route. Bewerley Park Outdoor Centre offers guided canoeing activities for beginners on the nearby Glasshouses Mill Dam, and How Stean Gorge organises group paddling sessions in the area.

Paddlers planning trips should check river levels in advance and identify the locations of weirs along their intended route. A British Canoeing membership includes a waterways licence covering access to designated stretches of UK waterways, which is relevant for planning access on the Nidd.
