For sale: 10 idyllic islands to escape to this winter

Ginger Island, British Virgin Islands.

If, like Richard Branson, you think your own private island would benefit your health and, like him, you have the odd Ј11m to spare, consider this. Ginger Island is completely unspoiled, meaning that it has no buildings, services or, indeed, any sort of port. If you are an experienced sailor, or able to dredge your own channel, the heart-shaped bay offers complete seclusion and fabulous potential. telegraph
