Paths here are not waymarked, and a detailed map and compass plus the skill to use them are essential, particularly in cloud on the featureless summit area. Weather changes quickly, with strong wind and severe windchill on the ridge, and snow or ice possible from October through May, when this becomes a winter mountaineering objective rather than a walk. Crossing Lingmell Gill can be dangerous in spate and may be very difficult or impossible during and after heavy rain, so check the crossing before committing to the climb. The Lake Head car park north of Wastwater is the main large parking area for this side, with toilets and a welcome centre, and the approach roads into Wasdale are narrow. An early start helps with both parking and the busiest stretches of path. Dogs are permitted but need to be fit for rough fells and under control near livestock; steep scree and gaps between summit boulders defeat many of them.
