In reply to Climbyclaudie:
In The Lakes Castle Crag Borrowdale is a nice short walk out of Grange and the path is pretty clear. Lots of interest on the way up.
For a "wow" factor view, Dale Head from Honister is a good one. Watch the quarry on the Left on the way up (easy to avoid). Up and down the same way. Cafe's in Buttermere are great afterwards.
The busier "family" ones include ones like Helm Crag out of Grasmere.
You should have a map to hand for any you do really, especially this time of year! Have a good one.
