South-west of Cornwall, the Isles of Scilly offer a staycation escape that’s a world away from the rest of the UK. Just over 2,000 people call its five inhabited islands – St Mary's, Tresco, St Martin's, Bryher and St Agnes – home, plus there are countless uninhabited ones to explore. Loved for its wild landscapes, unspoilt sandy beaches, clear blue waters and exotic gardens, Tresco is our pick – and is a year-round, car-free destination for those wanting a coastal break with a difference. Here’s where to eat, sleep and explore on the island, and what to know about the rest of the main isles.
