In reply to NobbyClark:
If I had the time which you seem to have I'd go for mungrisedale phone box to park but instead of following the path shown on the map head up the road a little to ravens crag. From here a path follows the ridge up to bowscale fell. It gives a great view of blencathra and also across the valley north to carrock fell. The going is steep to start with but well worth it.
From the top if bowscale there is another unmarked path that takes you straight to the marked path just north of sharp edge. This one isn't so clear in cloud go a little navigation my be needed but on a clear day sharp edge is visible all the way.
When you meet the marked path drop down under sharp edge to scales tarn for the night.
Great walk with even greater views
