The New York Times agrees, Cannes is great for strolling. (see NY Times article on best walks in Cannes).
The NYTimes' Top Walks in Cannes?
La Croisette, not surprisingly. The seaside promenade along the Bay of Cannes is the most photographed part of town. We enjoy it most in the late evening, when the sun sets and the city lights begin to glow.
The old town quarters of Le Suquet perched up above the port with its steep cobblestone streets (warnig: high heels nightmare!), its quaint restaurants, large and animated Forville marché and the Musée de la Castre for its incredible views.
AzurAlive's Top Walk around Cannes? :
The Island of St Honorat, a lush green jewel just beyond the Bay of Cannes. This rare and protected island is home to a monastery of the cistercian congregation. Monks live and work there in silence, cultivating plots of land, caring for the 19 acres or so of vines (Chardonnay, Clairette, Syrah, Mourvedre and recent Pinot Noir grape varieties).
Respectful visitors are welcome on the island, and it's a treat to walk along its footpaths. Set aside about 3 hours to soak in the sites of St Honorat, the scents of the sea, the pine needles, the flowers. And why not reserve a table for lunch at the main restaurant on the island, La Tonnelle.
It's a 20-mins ferry hop over from the old port of Cannes. Check out the current ferry schedule to St Honorat.
