Forum public beach is what I would call a "full service" beach as it has both a private beach-restaurant, Hi Beach, and plenty of public facilities to make a day at the beach comfortable. Also comfortable is the beach itself at Forum. While not exactly sandy, the galets are smaller than those on other beaches and interspersed with some sand.
Forum beach is in central Nice between Voilier and Neptune beaches and at the foot of ave Gambetta. As it's easily accessible from northern Nice, Forum is a popular beach and can be crowded on a summer day.
With lifeguards and a first-aid station, you can plunge into the waves in total security.See more about lifeguards.
There's very limited hourly parking available on the Promenade. Otherwise, there's the underground parking Palais Massena (04 92 17 54 42) a short walk east at 29 Promenade des Anglais.
The Gambetta/Promenade bus stop is on the Promenade across from Hi Beach. You'll find buses 8, 11, 52, 59, 60, 70, 94, 98, 200, 230, 400, 500.
There's a public showers and toilets next to the entrance to Hi Beach.
Right on the beach, there's Hi Beach restaurant. Across from Hi Beach there are two cafe-restaurants: Les Jardins du Capitol and Cocodile. Walk a block east and there's Pinocchio, a cafe that serves ice cream, sandwiches and drinks.
