Among the world’s most famous addresses, Sir Richard Branson’s private island can be rented privately for groups of up to 48 guests combining balconied bedrooms in the central Great House (some bunked and toy-filled with kids in mind), a Jacuzzi-boasting master suite and six beautiful, bijou Balinese pavilions scattered about. Still-larger parties can also take over nearby Moskito Island (sleeping 16), while individual rooms are offered during occasional ‘Celebration Weeks’.

Paradise awaits. The 74-acre isle is fringed by various bone-white beaches and snorkel-tastic coral reefs. Along its Main Beach, watersports such as kitesurfing, sailing, diving and paddleboarding are available; elsewhere, visitors can exercise in a gym, take Aromatherapy Associates spa treatments, attend sunset yoga or Pilates classes, play tennis, whizz along a zip-line, undertake helicopter and deep-sea fishing excursions or arrange guided walks in search of lemurs and flamingoes. Boredom? Not a chance.

Also Balinese in style, the focal Great House combines its bedrooms with a roof-terrace dining space affording wondrous sea views. Meals may also be taken at a sushi bar beside the infinity-style swimming pool or beachside, with the cuisine changing daily. All the while, admirable measures such as renewable-energy sources, organic orchards and biofuel golf buggies reduce Necker’s eco-footprint, meaning your only guilt will be at the Instagram photos you can’t stop uploading.
