Harden Beck is a stream that flows from Hewenden Reservoir, over Goit Stock Waterfall to the River Aire in Bingley, West Yorkshire.

Harden Beck is an overflow channel of Glacial Erosion which was carved out during the last ice age.

[2] The section after the waterfall down to the bridge under the road to Wilsden, is locally referred to as 'The Hidden Valley.

The Beck skirts the northern edge of Shipley Golf Course, through the ford and then under the bridge at Beckfoot before joining the River Aire in Bingley.

[17] Where the Beck curves between Ruin Bank Wood and Harden Grange is a Grade II listed footbridge.

[24] Goit Stock Woods and Harden Beck are listed as an SEGI (Site of Ecological and Geological Importance) by Bradford Council.

As the mill is now private dwellings, its goit was no longer necessary and as the weir was a barrier to fish passage, it was cut open.

Harden Beck was home to John Nicholson, The Airedale Poet, in the early nineteenth century.

[27] He is said to have written many works beside the beck and by Goit Stock Waterfall, which he often visited in the dead of night.

Developed by poet Simon Armitage and Tom Lonsdale, the walk takes in 47 miles (76 km) across moorland and water to inspire walkers.
