We went a couple of months ago for 4 nights and did most of the stuff on sgn23’s list. We had a car for a couple of days and with £10 of fuel did the whole island a few times!! We worked our way round the coast road and each bay one day.
Some of the beaches/bays are stunning. Its a nice place to just go and relax and not do much other than eat and drink. German bunker fish shop for lunch when the suns out is great, lobster, prawns, scallops, bread, salad, jersey royals and a couple of cans of pop for less than £20. Whats not to like? (seafood i guess if you don’t like it).
Lots of WW2 history, some of which is really interesting.
All in a great place for a few days but that’s about all you’ll want there.
