The "Three Peaks" of Whernside, Ingleborough and Pen-y-Ghent dominate the skyline of the western part of the Yorkshire Dales national park. Although not the highest mountains in the country, these spectacular dark fells tower over the surrounding countryside near Settle, Clapham and Ingleton, and they are of course very popular with walkers, ramblers and mountain bikers. Geologically, the Three Peaks are all of millstone grit, but on a limestone base, and the area is popular with cavers and potholers exploring the caverns which have been formed by the streams and rivers running off the fells. The tour takes us on an anticlockwise loop around Whernside starting from Ingleton and resting in Dent at the half way point. On the way out you pass through Scales Moor on the way up Whernside, here you will find the most amazing limestone pavements. If you have time at the end of your ride then Thornton Force and Pecca Falls are just up the valley from Ingleton and worth a visit.
