When there was a Cezanne retrospective in Philadephia several years ago, I went on my own and felt that it was like a pilgrimmage. Some of his earlier works are really heavy and ugly, showing a great deal of struggle. But the light and space and balance of his later landscapes are transcendent (I think). But many Freepers will disagree.
Portrait of Cezanne's father 1866 (an interesting contrast to a recent post about a portrait of Rembrandt's father being stolen).
Still life with Peppermint Jar, 1890. I actually like this still life, perhaps because it is most like a mountain.
Mt. Ste. Victoire from Bibemus Quarry 1880s.
I actually visited Provence and Aix in 2002. I was able to climb a bit of the mountain, kids in tow, and my husband went further (without the kids). It's a pretty busy town with few signs about Cezanne's studio, etc., so we never found that to visit. I expect the signs will be better this year. I'm tempted to return to see the show, or to plan a trip to D.C. There's something wonderful about his work; but it is really hard to explain.
