Hull Pot lies on the western side of Pen-y-ghent just to the north of the main footpath, the Pennine Way, which leads from the summit into Horton-in-Ribblesdale. It is also close to the route of the Yorkshire Three Peaks and is well worth a visit.
It is actually a collapsed cavern and there is little to explore underground. However, for walkers it is an impressive hole measuring 91 metres (300 feet) long by 18 metres (60 feet) wide by 18 metres (60 feet) deep. Just be careful close to the edge.
In dry weather Hull Pot Beck goes underground before it gets to the rim of the pot and resurfaces again as a waterfall below in the pot itself. The water then disappears again and re-emerges at Brants Gill Head, a short distance from the Pennine Way and Ribble Way near to Horton-in-Ribblesdale.
In very wet weather the stream runs over the edge into the pot, creating a spectacular waterfall. In fact, it has been known to fill it to the brim with the water overflowing and running down the hillside.
A guide book published in the late eighteenth century called it 'Hulpit'. The author said it 'would have appeared like the inside of an enormous old Gothic castle, the high ruinous walls of which were left standing after the roof was fallen in'.
