In reply to marko8182:
Seathwaite camping is was I was going to suggest, Within 10 mins walking distance you'd have Sour Milk Gill Boulders and also Marks Boulder with a few board like V6-V8's on, and further across the other way a 'newer' boulder with with a few cool problems on, including Lambrini girls which is V8 I think.
Then much further up the hill (30-40mins) you have Gillercombe, which has several boulders with a broader range of grades. The arete is a classic V5 which is very droppable even at the top, with a few cool hard sit starts to it as well.

Then, walking from the camp site down the road for a couple of miles (you might be able to catch the bus) is the Bowderstone, the place to go bouldering in Borrowdale and plenty to do in V6-V8 range.
