OK, it’s not quite Necker Island or the desert island of Robinson Crusoe, but Osea Island on the Blackwater Estuary in Essex is quite a remarkable semi-deserted private island. You have to stay for at least two nights to be able to visit this ‘exclusive luxury island holiday resort’, but once you’ve booked it’s a real adventure getting onto the tiny tidal island, accessed via a mile-long causeway emerging from the estuary for just four hours a day. Having made it across, the 380 acres of countryside, pretty village and four miles of beaches and coastline make it feel like another world. Bring your cozzie; should the grey waters of the estuary prove unappealing dip-wise, there’s a saltwater swimming pool on the island, and you can borrow a bike to cycle around it all.
Get there: By car in about two hours from central London, or by train from either Liverpool St to Witham, or Victoria to Colchester (and taxis from both to Osea in about 15 minutes).
