Ahh! We stayed in the little hotel that's directly below the old castle on the bluff. It's lit up pretty cool at night. Got some great time-exposure shots of it. Really nice town, Cassis is.
We actually went back through on our return from Avignon. I was looking to hook up with the local guide service, but couldn't work it out. So I ended up buying a French guidebook and soloing the low-5th stuff that Gaston put up. Great times, that trip was.
