All the good riding is inland, although the coast road should be less mental out of season. The Col d'Eze, the Col de Turini and the Col de Vence are all easily accessible. Not sure if Max Leonard is still on here but he rides there a lot so is worth seeking out on Twitter or Strava.
I'm heading to France next month, Nice in particular.
Does anyone have experience of riding there? road bike rental? or should I try n find a bike box?
Also any suggestions on places to visit?
thanks
