For the view shown in the photo below, you'll need a rental car. Take the 'Haute Corniche' and follow directions to 'Astrorama', the observatory. Once you reach the observatory, continue driving (the road will turn right) until you reach a parking area. A bit further on is a fort which was used in World Wars I and II. In this area you will find an orientation table which also gives an astounding view of the French Mediterranean coastline, and Eze. Best visited in late spring, early summer or late fall, when the sky is clearest. Midsummer and early fall have hazy skies.
