From LKyon, easy ! definitively go to south. week end in Marseilles, then around Marseilles, Cassis is charming little place with the 'calanques' on the sea.
Then when havce time go further visit Provence, le Luberon, etc
Train from Marseilles to St Raphael, Cannes, Nice
All French Riviera is exceptional.
North from Lyon you have the wineyards, Beaujolais, Bourgogne. Lot of places to visit. East from Lyon Annecy lake, Grenoble and the Alps
Lyon is nicely placed to go in many places, just need choose !
But we all know that u are in Lyon already and u got a French bf! When did u come bk to BJ?
