One of only four Lakeland fells above 915m (3000ft), the great hump of Skiddaw (931m) dominates Keswick's northern skyline. It's a long, steep and tiring puff to the top (slog is a fairly common description), but on a clear day the mountain's panorama more than matches the other three highest peaks. It's 8 miles return, or around five hours of walking.
Most people walk directly from Keswick, following the path over Latrigg (368m), Lonscale Fell (715m) and Skiddaw Little Man (865m), then descending via Carl Side.
As with most high peaks, 'Keswick's Matterhorn' is not just steep, it's also exposed, windy and very hard to navigate in fog and cloud – so plan accordingly, take a map and compass and know how to use them.
