Hazard: Moderate
A rounded top on the busy Coledale round, best known for the dramatic zig-zag path that climbs its eastern slope. The zig-zags themselves are well graded; the hazards lie either side of them: a steep, loose, eroded fall-line if you cut the corners, and the narrow, exposed neck of ridge linking Sail to Crag Hill. Keswick Mountain Rescue Team covers this popular ground.
- The narrow ridge to Crag Hill: The connecting ridge between Sail and Crag Hill narrows to an exposed neck. It is straightforward in calm, dry conditions but unnerving and slippery in strong wind, wet or ice — take it steadily and don't be rushed by the wind.
- The steep eastern flank (off the zig-zags): The famous zig-zags exist because the direct line is a steep, deeply eroded gully. Cutting the corners puts you on loose, steep ground where a slip runs a long way and you damage the path for everyone. Stay on the hairpins, up and down.
- Exposure and navigation on the open ridge: The whole Coledale crest is exposed to the wind and featureless in cloud. Keep a bearing between the tops, and remember this is a long, committing round once you are out on it.
Who should attempt this fell: Sail is one of the gentler Coledale tops as long as you stay on the path: take the zig-zags rather than the eroded direct line, and treat the narrow neck to Crag Hill with care in wind or wet. It is exposed, featureless ground in cloud, so keep a compass bearing, and pace the full round so you are not tired and hurried on the steeper sections. Full winter kit when there is snow or ice.
What to watch for: Slips on loose, steep ground when cutting the zig-zags · Being blown off balance on the narrow ridge to Crag Hill in high wind · Navigation errors along the open ridge in cloud · Fatigue late in the long Coledale round
