Ingleborough is the second highest mountain in the Yorkshire Dales, at 723 metres (2,372 ft). It is one of the Yorkshire Three Peaks, the other two being Whernside, at 736 metres (2,415 ft), and Pen-y-ghent, at 694 metres (2,277 ft). Ingleborough is frequently climbed as part of the Yorkshire Three Peaks Challenge, a 24-mile (38-km) circular challenge walk starting and finishing in Horton in Ribblesdale. If done anti-clockwise Ingleborough is the last mountain climbed, and ascent is from Chapel-le-Dale.
The second part of the name Ingleborough is derived from the Old English word burh, meaning "a fortified place"; in this case, a hill fort. On the top of Ingleborough the remains of an old walled enclosure have been discovered inside which foundations of Iron Age huts have been found.
Ingleborough is situated in the south-western corner of the Yorkshire Dales, being at the highest point of a large triangle of land with corners at Ingleton, Ribblehead and Settle. The hill is connected to its nearest higher neighbour, Whernside, by a low col or mountain pass at Ribblehead at approximately 296m.
