Have been there, would go back anytime. Great scenery, rather low prices and great cycling. And some fabulous old towns. End of june might be a tad on the late side regarding heat. Expect spectacular and long climbs rising right out of the sea. When I was there (2004) there were frequent police controls so have your identification at hand at all times. Wild camping is a bit iffy since about all flat parts of the land are allready in use. But there's an abundance of nicely priced hotels.
