Crimple Beck, also known as River Crimple, is a small river that flows through North Yorkshire in England. The river is approximately 10 miles long and is a tributary of the River Nidd. It rises in the village of Burn Bridge and flows through the towns of Pannal and Spofforth before joining the River Nidd near Knaresborough.
The river is known for its picturesque scenery and is a popular spot for fishing and walking. The surrounding countryside is home to a variety of wildlife, including otters, kingfishers, and herons. The river is also home to a number of fish species, including brown trout, grayling, and chub.
Crimple Beck has played an important role in the history of the area. The river was used to power a number of mills in the 18th and 19th centuries, including a paper mill and a corn mill. Today, the river is still an important source of water for the surrounding area and is carefully managed to ensure its ecological health.
