As the European weather warms, crowds flock to glamorous Lake Como in northern Italy. Those in the know stay at CastaDiva Resort & Spa, a stunning waterside retreat that could pass for a castle in a children’s storybook. A string of paths weave through the lush lakeside garden, connecting two private villas and 73 suites and rooms to the public areas. Pull yourself away from the views, if you can, and make time to visit the spa – the largest in the Lake Como area – for the ultimate in indulgent relaxation.
