I went in February and it was wonderful weather and not too busy. You can buy your entrance ticket at the gate. BE SURE to take your Iphone or device with a camera in because you cannot take a regular camera and must leave your belongings (ie Backpack) in a locker at the entrance. It is not in the main downtown area so I expect only people with a specific interest would go. No lines in February. Hope this is helpful.

you just need to go there. there are people who will answer any questions inside.

Probably. They are very welcoming to visitors. I would write ahead to make certain you have a reservation. The sinogoga is an amazing place.

I would say that if you write to the director of the synagogue beforehand or head Rabbii, that would be a tremendous help. I am the producer of a youtube show and to get an interview and most importantly be able to bring my camera into the place, I wrote ahead and gained special permission. That small gesture is very much appreciated by the people there. When I arrived, they were very, very accommodating.

Yes. We arrived there late on a Friday evening. They said there was no entrance unless we were attending the service. We then sat and listened and found it very nice. Then we realized we had something we had planned to do, and left. The guard was not happy and thought we had hoodwinked him. I felt very bad as did my companions, so unless you will stay a while, don't go unless you do not mind the anger of the security officer. For a lecture I was giving in 2014 I made an appt with the Director of the Synagogue and had a lovely chat with him and the Director of the Congregation. They were extraordinarily kind to me and my entourage. The Head Rabbi was, at that time, in NYC!!!

I would take a taxi. Enjoy your visit-it is very special.

no need to book in advance.
