I don't know exactly because the Trianon is a separate building. But I would say the gardens are open as long the Versailles gardens are open. So all day long till late evening. M.

Hello, You can rent the golf cart on the North terrace. The terrace is located behind the chateaux, on the garden side. You will also need a valid drivers license -- US works and it costs 32 euros an hour. Have a great time😁

Walking to the Trainon takes from 20 to 30 minutes, and all the way to the Hamlet around 40 to 45 minutes. You can also take a small train or hire an electric cart and drive up to the Trianon.
