Sergeant Crag Slabs with Black Moss Pot as a swimming option. Shepherds Crag with swimming either in the river Derwent at the Chinese bridge or in Derwentwater. Pavey and Dow also fit the bill.
In reply to rubisco:
Pavey is a good choice. There's a neat article on the crag - with some excellent Dave Simmonite photos - in the current issue of Climber
Might also suggest crags down in the Duddon Valley
> You've seen the way in Jaws people thrash about in the water to avoid getting eaten by the shark? That's wild swimming.
And wild camping is obviously only an option in areas with large dangerous predators such as polar bears which might rip into your tent in the night (wild swimming would obviously also be a possibility in such areas).
