Possibly the most isolated beach on this list, Skaw is located on the third biggest Shetland Island, Unst, and is the most northerly inhabited place in the UK. Given its distance from the rest of the country, the small sheltered sandy beach in Skaw is often empty. Of course, there are no beach facilities here, but it is a magnificent spot to spend some time and perhaps picnic with the family. The island is a haven for bird watchers with the Hermaness National Nature Reserve being home to huge seabird colonies including puffins and fulmar. But there are plenty of other spots around the island where enthusiasts can catch a glimpse of a huge variety of species, some of which are extremely rare. As well as birds, it is possible to spot seals, otters, whales and dolphins while prize-winning Shetland ponies are bred here. Muness Castle is one of the island's main attractions. Built in 1598, it was attacked by the French in 1627 but subsequently repaired and used by the Dutch East India Company as a storage facility. Another place of interest is the fabulously named Muckle Flugga Lighthouse, the most northerly in the UK and built by the father and uncle of Robert Louis Stevenson, who used the map of Unst as inspiration for that in his most famous work. The Unst Bus Shelter is perhaps the oddest attraction on the island. Saved by a seven year old boy who used it to get to school, it is furnished with a sofa and television and decorated comfortably.
