Although technically outside of the Yorkshire Dales National Park boundary, Nidderdale (along with the Washburn Valley as well as an area to the east of Nidderdale) has been designated as an "Area of Outstanding Natural Beauty" and has every right to be included in any definition of the "classical" Yorkshire Dales area.
Rising on the wild moors on the eastern flanks of Great Whernside and Little Whernside, the infant River Nidd flows out from the desolate and expansive moorland reservoirs of Scar House and Angram before (in times of relatively dry weather) disappearing underground at Nidd Sinks and rising again at Nidd Heads. [N.B. In times of relative spate some of the river takes the overground course along the otherwise dry river bed.]
Below Pateley Bridge the dale becomes much gentler in character as the River Nidd flows onwards to Knaresborough and out of the dale to an eventual union with the River Ouse near the historic English Civil War battlefield at Marston Moor in the Vale of York.
Attractions and places in and near Nidderdale include How Stean Gorge near Lofthouse and Middlesmoor towards the head of the dale, Ramsgill, Stump Cross Caverns near Pateley Bridge, Brimham Rocks near Summerbridge, Plumpton Rocks near Knaresborough, and Ripley Castle near Harrogate.
As a matter of convention, Nidderdale is often divided into what is arbitrarily known as "Upper Nidderdale" and "Lower Nidderdale" - lying upstream and downstream of Pateley Bridge respectively.
Unlike the Craven dales of the national park to the west the geology of Nidderdale is predominantly of relatively impermeable millstone grit rather than porous limestone, which is why the reservoirs of Angram, Scar House and Gouthwaite are able to hold water. However the limestone cyclothems of the Yoredale series are present as surface rock in places in Upper Nidderdale, and it is here that some significant cave systems such as Goyden Pot and Manchester Hole have formed in the limestone strata. There is also magnesian limestone to be found in Lower Nidderdale around Knaresborough.
