Hello from Wisconsin,
April and spring flowers.
My rule of thumb for where to go is: If it is in the tour books, it has too much tourist influence and not enough local influence. So while the Dordogne is in the tour books the two following rivers seldom are.
Not so far from the Dordogne is the Lott River which is less touristed than the Dordogne. And even more fun and less touristed is the Cele River and surrounding hills. Pretty much at the juncture of these two rivers is a great cave with prehistoric paintings at Cabrerets. Where on the Lott? Get into the Parc Natural Causses du Quercy.
If you are willing to driving into the center of Cahors, a famous, photogenic bridge across the Lott.
