The long-standing designation "The Three Peaks" is well known locally, and in past times nationally. However, there are now a number of "National" Three Peaks adventure challenges involving Ben Nevis, Snowdon and Scafell Pike. The epithet "Yorkshire" is therefore now commonly added to differentiate Yorkshire's Three Peaks from those.
Geology
In common with neighbouring fells, the Three Peaks are carved from an almost flat-lying succession of sedimentarystrata of Carboniferous age. The lower slopes of each of the fells are formed from massive limestones assigned to the Visean age Great Scar Group. The upper slopes of each of the fells are formed from alternating bands of limestone and mudstone grading up into sandstone, all of which are assigned to the Brigantian and early NamurianagesYoredale Group. These alternations are considered to be a classic British example of cyclothems. Differential weathering and erosion of the various bands has given Ingleborough and Pen-y-ghent a distinctive, stepped appearance. The summits are capped by Grassington Grit, a variety of Millstone Grit. Considerable areas of the flanks of each of the fells are covered by peat whilst other areas are blanketed by glacial till notably across the southern and eastern slopes of Pen-y-ghent. The Ribbleheaddrumlin field is considered to be one of the finest in England. Fringing Ingleborough on each side however are impressive areas of limestone pavement. Extensive networks of caves have developed within the limestone strata such as the White Scar Caves, and potholes which attract cavers from all over the country. It is home to England's highest waterfall at Gaping Gill, where the Fell Beck drops vertically down a pothole, into Britain's second largest cavern. The beck re-emerges further down the mountain adjacent to Ingleborough Cave, where visitors can take a guided tour of a floodlit part of the cave system. Whernside, being more rounded, is visually less imposing than its neighbours, but its summit is the highest point in North Yorkshire.
The Pennine Way visits Horton and crosses the summit of Pen-y-ghent.
The Ribble Way follows the River Ribble from its source near the foot of Whernside to its mouth near Preston.
The Three Peaks walk
The Three Peaks walk of Pen-y-ghent, Whernside and Ingleborough is probably the original three peak walk within the UK. The first recorded ascent of the three hills was in July 1887 by J. R. Wynne-Edwards and D. R. Smith in a time of 10 hours. The walk covers a distance of to circuit of all three peaks with nearly of ascent and descent. A challenge that many walkers aim for when undertaking the walk is to complete the walk in under 12 hours, though as Alfred Wainwright says in his book Wainwright in the Limestone Dales, "Some participants have chosen to regard the walk as a race, and this is to be greatly regretted, walking is a pleasure to be enjoyed in comfort" . The route most walkers take varies from the fell race in that most traverse the 'nose' of Pen-y-ghent from Brackenbottom Moor and do not ascend from the Pennine Way. Additionally, Whernside is generally traversed along the right-of-way to the east, initially following the railway line, all of which can add extra distance to the route. For most people the route starts in the village of Horton-in-Ribblesdale, though many start from various points in the circular route, such as Chapel-le-Dale. Historically Chapel-le-Dale was the starting point though this probably changed when the Pen-y-ghent Cafe started running their clocking in and out service for walkers in 1968. The cafe is currently closed and as a result walkers can no longer register the beginning and end of their walk or pay to join the Pen-y-ghent Cafe's privately owned 'Three Peaks of Yorkshire Club'. The Yorkshire DalesNational Park runs a voluntary Friends of the Three Peaks project. The proceeds of this go towards the upkeep of the paths on the route. Certificates, medals and membership forms are awarded by local participating businesses.
The walking challenge
Understandably the Three Peaks Walk is seen by many as a challenge and it has become very popular for charity sponsored walks and Saturdays in early summer can see several hundred walkers make their way round the route.
The races
In addition to it being seen as a walking challenge it has also become a race for fell runners and cyclo-cross cyclists. However, there is no bridleway access to the peaks so any bicycle access is on a permissive basis on race days only.
, is a 70km self navigation trails ultra marathon held annually in October. Starting in Hawes, joining the classic Yorkshire 3 Peaks route around Whernside, Ingleborough and Pen-y-ghent. Returning to Hawes via The Pennine Way.
Media
The Three Peaks were featured on the TV programmeSeven Natural Wonders as one of the wonders of Yorkshire.
