We almost didn't go to Versailles on the weekend because we were worried about crowds but we did want to see the fountains and boy are we glad we did. There are many fountains situated all over the grounds. Some you have to find by walking into formal garden areas. You will need to walk a ways down the hill to see them all. All those fountains flowing are just beautiful. We didn't find the palace all that crowded and once you are outside it is so spacious that you won't feel crowded at all.
Be sure to go all the way down the hill and to the right to the Queen's Hamlet. You get to it from Petit Trianon building. This is a village of quaint, thatched roof cottages and other buildings built for Marie Antoinette because she missed her own village.
