In reply to olliejackson:
Some suggestions. Wasdale is the best climbing centre in the Lakes if the weather is good. You'll be able to get to Scafell, Great Gable and, after a bit of a walk, Pillar.
However, if the weather isn't good then there's not many options so you need to be flexible. I'd plan to bus/train it to Borrowdale then if the weather is set fair, go and camp at Styhead Tarn, have a day or two's climbing on Gable before descending to Wasdale. If the weather isn't so good then you can stay in Borrowdale where there are far more valley crags and the distractions of Keswick.
As for routes on Gable, if you are comfortable leading VD then do Arrowhead Ridge to begin with. This has the advantage of an approach walk which takes you past all the main climbing areas on that side of the mountain so you can identify other routes you like the look of.
Assuming you find Arrowhead Ridge well within your ability you can then retrace your approcah route and could, in order of arrival do some from Abbey Buttress (VD), Eagles Nest Ridge (MVS) (if you are confident climbing 4b above a no 2 rock) and Tophet Wall (HS). All are serious mountain routes so it is taken as given that you are confident route-finding and setting up bomber belays. Innominate Crack (VS 4b) is another good route.
I've deliberately left out Napes Needle as it requires some interesting rope techniques to belay on top and protect the descent - refer to Needlesports website for full story.
If multipitch VD is well below your normal grade, then just pick out routes in the order that you arrive at them ie something on Kern Knots, Tophet Wall, then the Napes. I'd still recommend Arrow Head Ridge - you could ascend it with sacs as your last route of the day and finish on the summit of Gable.
Once you've enjoyed some routes on Gable, descend to Wasdale Head. There's camping at the pub (don't think the facilities are up to much), or a little further down the valley at the National Trust site - showers and shop.
Next I'd head for Scafell. Assuming you're climbing around VD - S (if you're climbing harder then you can sort out some routes for yourself - there's more 3 star routes at VS and above than you can shake a stick at) you could do a route on Pikes Crag (big crag on your left, catches the sun) such as Grooved Arete (VD) carrying your sacs. This will leave you but a short walk from Mickledore where you can leave sacs and head for a route on Scafell. Pisgah Buttress is good at MS. Slingsby's Chimney followed by the Knife Edge Arete to the top of Scafell Pinnacle is well worth doing.
If you find these easy then Moss Ghyll Grooves is just MVS because of a couple of well protected 4c moves on pitch 2, and imho the best route of that grade on Scafell.
Pillar involves a long walk in (around 2 hours) but is another superb crag. Classic routes in the easier grades are the North Climb (HS - can't comment as I haven't done it) and New West - superb VD. The descent, especially from High Man where New West finishes is complex involving descending a moderate climb - Slab and Notch. There's a post on here somewhere where Stephen Reid recommends ascending then descending this as a first route so that you're familiar with the descent.
