Ingleborough, in a stunning Yorkshire Dales landscape. This is the second highest mountain in Yorkshire. It is part of the Yorkshire 3 peak challenge. Around the mountain the limestone pavement can be found. But below ground is equally as fascinating; as well as forming an artificial pavement on the surface the weathering over the years has formed deep gorges. The area is awash with potholes, and underground rivers, tunnels and caves. Making it a magnet for potholers and walkers alike.
