Visiting the Notre Dame is a must when in Paris. You can go inside, cimb the tower, and get a great view of the city. It's tough to get a great shot as she's surrounded by trees (and people!) , but if you head to the bridges East along the Seine you can get a great view of those flying buttresses :) Don't miss the love locks on the bridge nearby..
