I will be part of a week-long walking tour along the Riviera and based out of Antibes. I get the afternoons and evenings free, and I am quite interested in seeing the Gorges du Verdon. Obviously, it is my vacation and I can choose to go my own way and take a day off from walking with the others. I see various tours but they are all 8-9 hours. Is it possible to visit them in 1/2 a day on my own? I don’t want to rent a car, though.
Is it something I might be better off saving for a return trip?
