Try The Casquettes-only 8/9 miles from Braye harbour.
Great war time stories about this place. Alderney and the islands occupied by the Germans in WW2-the Casquettes likewise. Garrison at the lighthouse were asleep one night when the Allied Special Forces popped in and captured the lot-took them back to Blighty. New garrison put on lighthouse, naked, to keep them awake. Trouble is they all huddled inside to keep warm and Allied Forces raided the Casquettes again!
Care crossing The Swinge (current can be vicious) though, and look left and right when going past Burhou (the ferry from UK).
