Axo-
I went clockwise around it starting in Chambord which is at about 7 o'clock. Alma is the largest city on the lake and is at about 3 o'clock. Yes, from Alma, down around to about 6 o'clock it is more built up and less scenic, hillier too. Definitely worth doing, especially since there is a bike carrying train from Montreal which is worth a trip in itself. One kind of neat thing is that, since the land is so flat, and is was settled by Catholics, you can see the church spire of the next town miles before you get to it.
