Only 20 minutes from Nice you can find the city of La Turbie where a very nice walking tour begins, called La Tête de Chien. If you like nature and you are obsessed with walking you should definitely visit this place because it is just simply amazing. From the top of this 550 meters high promontory you can have a look at Monaco and Monte Carlo, including the football stadium, the casino and the port. On the way down you can enjoy the natural environment, the beautiful flowers, trees, etc. and watching at people climbing. Once you’ve arrived at the bottom of the hill if you have enough time you can visit the modern seaside resort of Cap d’Ail before going up again.
When you look up at the mountain don’t be afraid! It seems more far than it is! Good luck! 🙂
