10. Isle of Skye, Scotland

A row of pastel-hued 18th-century houses along the harbor in Portree welcomes passengers to this wild and windswept Scottish island. A visit in late August or early September reveals rolling hills carpeted in purple heather — but spring and summer are perfect too for sipping drams of peaty Scotch and sampling local salmon, lamb or — if you dare — haggis.
