Colline du Chateau translates as “Castle Hill” and, once upon a time, there was indeed a castle up here. All that remains now are the ruins but they are open to wander through at your leisure. One of the parks most impressive features is the large waterfall that cascades down over a short cliff.
The summit of Colline du Chateau is at 93m and you can walk up either from the old town of Nice, from the eastern end of Promenade des Anglais or from the port area. There is also an elevator which you can access at Quai Rauba Capeu at the far end of the Promenade des Anglais.
