10 of the best: uk beaches - 8. Wales: Marloes Sands, Pembrokeshire
The wow factor: Measuring just a mile and a half long and half a mile wide, Herm boasts several exquisite beaches, with Shell Beach being the pick of them. The sweep of golden sand stretches almost three-quarters of a mile to Herm’s northern tip and around to dune-flanked sandy bays. It is named for the millions of tiny shells washed up by the Gulf Stream.
Activities: There are no cars on Herm, so walking is popular. You can go kayaking, fishing, charter a boat, go on an island RIB wildlife adventure, tour Herm’s gardens and discover its history. Go rock pooling on the beach.
Stay: Herm has one 40-bedroom hotel, 20 holiday cottages and two campsites. Stays at the White House Hotel, including sea or air travel, are offered by Channel Islands Direct (www.channelIslandsdirect.co.uk).
