This is a great topic. It's good to know there are so many truly beautiful campuses all over the country. I cannot think of any that qualify here in FL, our latest home. Previously we lived in AZ, and for all the scenic vistas that the state offers, there are no really outstanding campuses, though (as someone mentioned) U of AZ is nice.
I graduated from Holy Cross in Worcester, and if you can get past the fact that the only views are of Worcester, the campus is really nice. They generally win awards for the plantings. The thing about it is that it's on a hill. It is hard to contemplate beauty when the walk from your freshman dorm to your first class requires walking something like 35 flights of stairs, ups and downs alike. That is my recollection, at least.
