Three hours and 42 minutes from Poole to Guernsey via ferry and then 55 minutes via ferry from Guernsey.
Located between Guernsey and Jersey, this teeny island has banned cars, making it as peaceful a holiday as you’re going to get in the UK (it is weirdly UK territory despite being just a few miles off the northern coast of France).
There’s all sorts of wholesome activities to do on Sark, from the beautiful La Seignurie Gardens to cycling La Coupée. There are plenty of activities planned by locals, like yoga, stargazing or taking a trip around the island in a traditional fishing boat.
The beaches are unrivalled. Check out Derrible, Dixcart and Greve de la Ville (but do remember it’s the Atlantic and the water’s unlikely to be super warm). If you’re looking for something a little different, hunt down the Venus Pool, a natural rock pool only accessible two hours either side of low water.
