Villa Estate at Moskito Island, British Virgin Islands While you may be familiar with Necker Island, Moskito is the newest addition to Richard Branson’s ultra-luxe Caribbean portfolio, an exceptionally private, 125-acre destination in the heart of the British Virgin Islands. The Moskito portfolio actually includes three villas, the Branson Estate, the Point East and the Oasis Estate, all of which can be rented separately. In short, it’s one of the most exclusive private islands in all of the Caribbean.
