Marjorie Williams' MARKETS OF PROVENCE. Its not just markets but historic background, monuments not to be missed, restaurants and regional specialties. My other general guidebooks got left behind. Marjorie's book is more fun. Just 4.5" by 6", its lightweight, easy to pop in your bag, though I admit to ripping pages out and marking them up with abandon for easy access. For more info on Marjorie please visit her web site. I reviewed her MARKETS OF PARIS here.
Fondation Vincent Van Gogh. Normally they get just ONE painting each summer to exhibit so this is a don't-miss opp.
