The kids will sleep soundly after a fun day out at Plage des Pissarelles. Hunt for crabs and other little critters, stick a toe in the water or maybe even fly a kite!
You'll find this stretch of coastline in Cap d'Ail. Once you've done everything you want to at Plage des Pissarelles, consider visiting nearby Casino Monte Carlo, Cours Saleya, and Marc Chagall National Museum.
