Being born in Guernsey, Channel Islands I decided to bring them a little closer to me so have created a Channel Island Loop hiding 6 containers each named after one of the Islands. The Channel Islands were the only part of the British Isles to be occupied by the Germans during WWII
'SARK' is a beautiful island almost with a small annexe 'Little Sark' which can be reached across a small bridge ( Le Coupe) situated atop a rocky extension. Again no motor vehicles allowed but horse drawn carts will transport you around if you wish, otherwise walk/cycle.
