In reply to oldcheese:
Not as far as you may think and it is THAT good. The A66 means it's only 30 mins from Keswick. More of a walk in than Carrock but a late morning arrival will see you in the sun ( if there is any ) until night time.
You don't say what your group of non climbers consist of. Families with pushchairs and dogs or outdoor enthusiast who've just never climbed before? There is a lot for the latter to do in the area.
If they are adventurous they can come down the approach with you. It's very steep ground with in situ knotted ropes for aid. Once down they can explore but not a right lot else. Lots for non climbers to have a go at though. There's literally tonnes of stuff at V0 and below that's not documented.
If they are going to be total non climbers they can walk along the top of the cliff to the RSPB birdwatching points and on to Fleswick bay whic is a great spot for a picnic, and also has bouldering but VERY tide dependent. If the water has recently been up to the cliff base the pebbles can be 5-6ft lower than normal and what were V1 sit starts are now V6 standing starts.It's a great beach for rock pools, exploring ship wrecks, picnics and sunsets.
There's also St Bees itself just down the road which they could amuse themselves at while you climb.
No idea as to the conditions of Carrock at the moment but it can get very cold and very boggy.
