El Hierro, Canary Islands, Spain
The smallest and least known Canary Island is 'the delightful isle of El Hierro', says Stuart. 'Once considered the end of the world, it still feels remote and untouched. Down at sea level the coastline consists largely of wave-battered cliffs, but the south offers world-class diving and the north has a series of natural swimming pools that are like oversized rock pools ideal for all the family to swim.' Great for those on a budget, deals are available from £250 per person for a week.
