The AONB includes all of Nidderdale except a small area in the lower dale around Hampsthwaite. In the lower dale, below Pateley Bridge, attractions include Brimham Rocks and the Coldstones Cut. In the less populated upper dale there are a series of reservoirs, Gouthwaite Reservoir (a nature reserve), Scar House Reservoir and at the very top of the dale Angram Reservoir, dominated by Great Whernside and Little Whernside.
