I'm wanting to visit the gardens of Versailles as we travel from our Eurocamp to Disneyland. I can't work out if I need a ticket or not--on the internet it says the gardens are free...but online it loos like there are tickets. Has anyone been and can explain? We don't want to go in the palace as we have 5 children and it would be stressful but would like to see the palace from the outside and visit the gardens. I'm happy to book tickets but just finding ti hard to navigate
