Offering a wealth of outdoors wonders both in winter and summer, the White Mountains are a thrill for all seasons.

Nice has a cosmpolitan Riviera vibe, and you'll enjoy exploring its fashionable boutiques and restaurants and sunning yourself on its popular beaches. (Just don't expect soft sand—these beaches have pebbles.)

Spring and summer show this lush area at its best, but cross country skiing opportunities make a good case for winter visits.
