Very pretty and laid back site. Well sheltered with good facilities and fairly good environmental credentials. Situated near some very good beaches and an excellent beach side bar. Close to Redruth for your pasties, and they prob sell them on site. Bile hire available and situated on a good family friendly bike trail.
Some reasonable bouldering near by at Carn Brea and Gwithians beach.
