The crags are on the west (east facing) side of the gorge at the head of the Linn. They extend for some 100m, emerging out of the wooded hillside at their left (south) end and gaining in height to reach almost 30m at the head of the gorge. The rock is sandstone of a vertical and overhanging nature, varying in quality. The crags are in a very sheltered situation and stay dry more often than not in bad weather. One significant route lies on the opposite side of the burn - the famous overhang.
Fell Sandstone Carboniferous, Dinantian
Overgrown, mossy and generally very poor.
It should be noted that Hareshaw Linn is now in National Park ownership and is an SSSI. Due regard should be given to maintaining its special environment.
Although quite long, the routes are not of the highest quality. Many are loose and on poor rock. Perfect for would be Mick Fowlers.
No recorded problems.
Hareshaw Linn has warranted mention in the "Other Crags" section of the last four NMC guidebooks on the strength of one route; the Main Overhang. Pegged in 1962 by J. Sloan it climbs the big roof on the crag on the east side of the stream at the head of the gorge. In the early 60's Maclolm Lowerson, whilst on a trip to do the Overhang, noticed the crags on the opposite side of the burn. It took him until the autumn of 1992 to return and investigate these quite high buttresses.
