re: Cliff Diving in the Cinque Terre?

I've done it. In Montessori (check the spelling, but its where we stayed and its one of the 5 cities that comprises it.) you can cliff dive. I think a girl from LSU actually died doing it a year or two after we did it, but its about a 60-70' drop, into some deep crystal clear water. It's awesome. We jumped all over the place.

FYI, skip Venice and spend more time in the other towns you mentioned you are going to.
