The Ingleborough Estate Nature Trail wends it way past a lake, along a steep river valley through beautiful woodland to Ingleborough Cave. It is the gateway to some of he Yorkshire Dales National Park’s most stunning limestone scenery including Trow Gill gorge, Gaping Gill pothole, the limestone pavements, Norber Erratics and ultimately the summit of Ingleborough Fell. It was established in 1970 to mark European Conservation Year which coincided with the 50th anniversary of the death of one of Clapham’s most famous sons, the plantsman, plant collector and writer Reginald John Farrer (1880-1920).
