Great in summer
The Promenade (Spanish for "boardwalk") is great in summer (you absolutely have to go to the beach), and you can tell its popularity by the amount of people who walk, bike, and skate, there. People in groups, people alone, people with their dogs. During summer, there are also "traveling shows" and lots of nightlife since the Nice beach is just below and you can enjoy a panoramic view of the sea. In winter it is also nice to just go for a walk or just sit down and enjoy the views.
