You can't really miss the promenade. Whether you intend to eat an ice cream and people watch; saunter up towards the old town from the famous Negresco Hotel; or rollerblade / cycle along the sea; this is a fabulous place to spend time.
There is a rollerblade hire shop towards the old town end of the promenade and the city of Nice has a cycle hire scheme with bicycles stationed throughout the city (Velo Bleu).
The promenade pretty much extends from the airport to the port.
