Nice's signature attraction is the Promenade des Anglais, a bustling walkway running along the Mediterranean. A walk up to Castle Hill is rewarded with a vista of the city, the Bay of Angels, pebbled beaches and the azure water that gives the Cote d'Azur its name. Nestled into the hills rising up from the shore are narrow streets, red-tile roofs, churches, outdoor markets, al fresco restaurants, parks and dozens of museums. The bay lights up after dark to usher in Nice's vibrant nightlife.
