Piers Gill runs below the eastern crags of Lingmell in a deep ravine, one of the finest in the District. Averaging about 30 ft, but much deeper in places, it pursues an L-shaped course down the fellside before emerging from its cutting to merge with Greta Gill. The scenery of Piers Gill and Lingmell from the Corridor Route ascent of Scafell Pike is remarkable and a faint path follows the eastern bank of the gill giving even more intimate views. The ravine appears to offer access at either end, but ordinary walkers should on no account attempt to follow it. Crossings of the ravine should also be considered impossible for the average hiker.
