how long is the actual guided tour.
If train at 9:15am, when return?
Hello, the tour lasts 3 hours total, that includes both the visit of the palace and the gardens, the 3 hours are fully guided. These 3 hours do not include the travel time, approx 30 - 45 mins on the train each way. If you leave Paris at 9:15am then you will finish in Versailles around 1pm, and need around 45 mins to get back to central Paris. There are also many other wonderful things to see in Versailles if you want to stay longer, and your guide will be happy to offer suggestions. You can head back to Paris on the train any time you like, it's very straightforward, trains leave every 15 mins and they all go back to Paris city center. I hope this is a help!
The tour started around 10 and wrapped around 1:00.
