For sale: 10 idyllic islands to escape to this winter

Hidden Bay Retreat, Alaska 

Three hours from Alaska's west coast cities, this three-bedroom house comes with 46 acres of woodland and shoreline, accessible only by boat. 

Not strictly an island, it is the only piece of habitable land within a million acres of forest. There is separate guest accommodation for all the people who will want to come whale watching with you during the long summer days. .telegraph
