Isle of Wight, great in the summer, plenty of places for a tent, plenty to see on a rib, plus you have the solent and to the west Jurasic Coast, Poole etc.
Thanks guys .. anyone been further afield .. say west coast of France, they've always looked lovely when you paddle round in the summer, but am concious of the big rocks every where .. they don't call it the Granite Coast for nothing !
