Why visit Grasmoor?
The broad, imposing mountain above Crummock Water and the north-western fells. The summit is at approximately OS grid reference NY 17485 20351 (latitude 54.571618, longitude -3.277879). These coordinates describe the summit rather than a car park or walking route.
The surrounding ridges can offer extensive views in clear conditions, but visibility and safe footing may deteriorate rapidly. Treat this as a serious fell outing rather than a signposted tourist attraction.
Walking routes to Grasmoor
There are several possible approaches to Grasmoor. Choose a complete route that matches the weather, daylight and your group’s mountain experience. The suggestions below are route ideas, not verified GPX tracks; confirm your ascent and descent on a current Ordnance Survey map.
Approach from Lanthwaite
From Lanthwaite near Crummock Water via an established but steep ascent. Check parking, path rights, local closures and the return journey before leaving. Exact distance and ascent depend on the full route chosen.
Ridge and alternative approaches
From Coledale Hause on the Coledale ridge. Longer ridge traverses should be planned with escape options and sufficient daylight. Do not rely on an unverified route line or a straight line between summit markers.
Terrain, navigation and mountain safety
Grasmoor lies on exposed upland terrain with potentially steep, slippery, rocky or pathless sections depending on approach. Conditions can change quickly, especially in poor visibility or strong wind. Carry suitable clothing, map and compass, food, water and a headtorch; snow and ice can require winter skills and specialist equipment.
Check the latest Lake District weather and travel alerts and a mountain-specific forecast. Summit coordinates alone are not a safe navigation plan.

Getting to Grasmoor
Approach area: Lanthwaite or Braithwaite. Check the access arrangements for your chosen route rather than navigating directly to the summit by road.
Summit grid reference: NY 17485 20351. Summit coordinates: 54.571618, -3.277879. These are for map identification, not parking directions.
Use official car park and public transport information where available. Respect narrow lanes, working farms and access restrictions.
Check conditions before your walk
Allow enough time to ascend, descend and deal with unexpected delays. Know your turning-back points and leave your plan with someone. Weatherline and mountain rescue guidance can help you prepare, but they do not replace sound navigation and judgement on the fell.
