The Route Napoléon
Route Napoléon is the route taken by Napoléon in 1815 on his return from Elba. It is now a 325-kilometre section of the Route nationale 85.
The route begins at Golfe-Juan, where Napoleon disembarked 1 March 1815, beginning the Hundred Days that ended at Waterloo. The road was inaugurated in 1932; it leads from the French Riviera to the southern Pre-Alps. It is marked along the way by statues of the flying eagle symbol (source).
One of these days!
