Herm is the smallest island in the archipelago that can be visited by the public, although not the smallest inhabited island. Like Sark, it is blissfully car-free, but unlike Sark the island even goes so far as to ban bicycles. However, the locals are allowed to use tractors. Herm is 3 miles from the coast of Guernsey and measures just a mile and a half by half a mile, so a visitor would have to be supremely lazy to want to drive around the island! There are a number of accommodation options for anyone wanting to stay overnight.
