The climb begins at the southern edge of the hamlet of Gayle, North Yorkshire, England:

Gayle, originally a farming settlement grew in the late 18th century due to employment in local quarries, coal-mining in Sleddale and in a water-driven cotton mill on Gayle Beck.  Wikipedia - Gayle, North Yorkshire

RoadCyclingUK.com writes of this climb:

“Yorkshire’s highest road is also one of the white rose county’s most iconic climbs, despite the Tour de France missing out Fleet Moss when cycling’s greatest race was in town in 2014.

Where cycling’s elite wouldn’t go up, however, plenty of others have – and the long, exposed climb with an unrelenting average gradient of 8.4 percent is a staple of any cycling trip to the Dales.”  

CyclingUphill.com writes:

Fleet moss from Hubberholme (from the south) is slightly easier than from the north side. The gradient isn’t too steep – 17% at its maximum. However, it is long and persistently hard and is preceded by a long drag from Hubberholme. From Hubberholme to the top of Fleet Moss is 12 km, with total elevation gain of 400 metres. (net gain 240m to 602 metres). Those 12 km are at an average of 3%, but with some downhill thrown into the mix.”

This climb is in the middle of Yorkshire Dales National Park, which attracts over eight million visitors every year.  The park is 50 miles (80 km) north-east of Manchester; Leeds and Bradford lie to the south, while Kendal is to the west, Darlington to the north-east and Harrogate to the south-east.”  Wikipedia - Yorkshire Dales National Park.
