It is so easy to stroll into France, many visitor cross the border without ever realizing they’ve been abroad. Instead of a coastal hike, the French Riviera offers a paved path that takes travelers from the Principality to Mala Beach on the Cap d’Ail. Catch the Sentier Littoral (coastal trail) at Marquet Beach and head west through a landscaped paradise dotted with mysterious mansions and eccentric estates. It is an easy walk for young children, with plenty of picnic stops and, during the summer, even restaurants on the beach. Hike, or catch the bus back from the downtown of lilliputian Cap d’Ail.
