Versailles fountains. How late are they working in the fall?

This would seem to be what you are looking for? Click on the tabs (casting, venue, dates and times, rates, etc.) for the most complete information:

Do note that they only operate on the days and hours indicated, and it costs extra to see them.

Thanks, yes I know about the hours, prices, days, etc. I'm just interested in when this ends before the Winter.

Did you go? Was it worth it in your opinion?

The front page of the website says "..until October 29, 2017."

All the fountains do not operate at the same time. Not enough pumping capacity, They cycle on and off on a set schedule for about 15 minutes to canned music. The Neptune fountain only operates once at 5:20 pm.

Thanks, I didn't see that. We were there in early October in 2015 and it was closed up completely for the winter. Great to know. Thanks.

I suspect that if the weather turns cold early, then they would shut off the water and cover up the fountains for the winter. That may have been what happened when you were there before.

As to whether the fountain show is worth it, that is completely subjective. If you really want to see them operate and as the Sun King would have seen them, then yes. If your interest is in passing, then it may be more crowds and hassle than it is worth.

PS - The fountains never all operated at once. As the king moved around the gardens the staff would turn fountains on and off respectively.

We saw them at the end of October 2015. They were shutting down at the end of October that year.

I guess I just didn't understand how it all worked. Thanks for writing back!
