La Vélo Francette is one of France's newest long-distance signposted bike routes. It links Ouistreham (Caen) in Normandy to La Rochelle on the Atlantic Coast.
Difficulty: Easy - moderate. This is a great route for families abut also for long-distance road riders. It mixes voies vertes (greenway routes) with quiet back roads. There are some hilly sections but if you take your time, it's more than achieveable for newer and less experienced riders. Choose the westerly diversion south of Caen if you want to avoid the most difficult stretches.
I rode this route in 2015 just before it opened.
