Brimham Rocks is a National Trust site on the high moor above Nidderdale, about eight miles south of Ripon. The moorland is scattered with enormous boulders of millstone grit that have been eroded over millions of years into extraordinary shapes — stacks balanced on impossibly narrow bases, arches, overhangs, and towers that look more like deliberate sculpture than natural formation. The largest rocks stand ten metres high.
It is excellent scrambling country — the rocks are low enough to be climbable without specialist equipment, and children in particular find it irresistible. The views from the higher points extend across the whole of Nidderdale and on a clear day as far as the Yorkshire Dales to the north. There is a small National Trust car park; arrive early on summer weekends to avoid the crowds.
