The weekend of 4th - 6th August is Sidmouth Folk Week, and camping should be easy enough at either Salcombe Regis or Kings Down Tail, and what's more there's a bus service that runs from both. Not expensive and of course the fringe is varied and enormous. Can highly recommend it. If you come you'll find me in 'The Bedford', but the Middle Bar, The Swan, The Radway and many others are just as welcoming.
