In reply to guy127917:
Last summer we spent 5 weeks with a camper van.
Drive to the alps and followed the Tour de France for a week, rode up Mt Ventoux, ferry to corsica, ran the GR20 in 8 days, few days cragging and beaches, ferry to Italy, Grand Paridiso NP walking and eating Italian food, Chamonix trail running for a few days. The first day of crap weather was the day we headed home. Lovely trip.
Perhaps not so much climbing as you want, but probably a lot cheaper if you avoid camp sites.
