Ah, one of my specialist subjects! I used to live outside Caen and worked in town for a while. Great part of the world.
As mentioned above, Suisse Normande is the way to go. It's called that as it's like being in a little version of Swtizerland. Stunning part of the world, some lovely riding too.
In the area directly around Caen there's little of any interest, unless you're on a road bike. Some nice bars and cafes in Caen, though (Rue de Bras is a nice spot, as is the area around the port, quai Vendeuvre. Up by the castle there are some lovely restaurants as well)
Ahhhh, happy memories of warm summer evenings in Alencon…….in the Mayor's garden….. 😈
