One of my favorite plans when I visit a new city is to go as high as I can to get a panoramic view of the place. When I visited Nice back in January I read that the Colline du Chateau overlooking the Baie des Anges offered an amazing view of the city. So I climbed all the stairs and after a good walk (later on I found there was an elevator, but never mind) I was rewarded with an amazing view of the old town, the bay and the sea.
