Yes, generally speaking, the Old City will very much require at the very least long lines of simply standing and much walking. The terrain is varied and cobblestoned, with various inclines and declines, just about every you go. It will be challenging but not impossible if you come rested and ready. You can definately taxi to Jerusalem (plan on roughly an hour there and back, 280 Shekels cost) However, taxing within the walled Old City won't be doable as the vehicles only drive along the edges/border of the walls. The Garden tomb is outside of the city, so you could go there and then taxi to the just inside the Old City, probably the Jaffa Gate entrance. If you have only a day I highly suggest thinking about what it is you truly hope to get out of this visit. Jerusalem, as a Christian pilgrim, really should be about moments of reflection, contemplation, prayer as opposed to the usual "quick selfie" stylings of other tour spots. So when you pray and read your bible, what moments from the Gospel really stand out to you? Then pick maybe 2 of those moments and try to get there to spend some quality time. Areas of interest are honestly going to be fairly spaced out. The main attraction of the Christian Quater would have to be the CHurch of the Holy Sepuchler (but if you're aiming for the Garden Tomb, I take it you are not of the belief that he was entombed at the Sepchler so no need to go there?) If you're aiming for more time where Jesus likely walked, perhaps a taxi visit to the Mount of Olives just outside the city to vist the Garden of Gethseme (with 2,000 year old olive trees) and the beautiful Basillica of All nations nearby. Or maybe not visit Jerusalem at all and head north to the beautiful Sea of Galiee area where his ministry began in earnest. Some amazing sites up there easily transverable via taxi. My take away is this. Visiting the Old City for a day is not ideal (but really, what place is sufficient in a day?) but doable. As a disabled person, you will be challenged so take your time and decide on what you really want to see. The Way of the Cross will likely be too challegening for you. Do you enjoy church visits? If so, there are plenty of many denominations? A suggesting might be to visist the Cenacle (the Upper Room Last Supper). In that immediate area you have the Tomb of the Virgin Mary, the Upper Room, as well as the Tomb of King David so you could get some Jewish culture as well as you see them intently praying at the tomb. Lots of decsions and you can't really go wrong as long as you go with patience and the right attitude. Have fun!

Sorry, spreche zu wenig Spanisch

The safest route to walk is via the Armenian quarter. (NOT through the shuk) rather through the Jewish residential quarter upto the police station in the Armenian quarter and out through Jaffa gate. This is a very busy route travelled by many so you'd be in good company. That being said, as a religious person myself who does not travel in vehicles on the Sabbath I cannot advise you on transportation. I know many of the taxi services do close for the Sabbath and don't know the other ones, so I can't vouch for them as I am unfamiliar. The walk to machane Yehuda market is about 20-25 minutes and very pleasant. On a busy route, so I believe you'd be safe. Of course I don't know what time you are planning this...so obviously within reasonable timing with pedestrian traffic around. I hope this helps

Yes I agree it is not safe but yet it is safe. What do I mean by that, Jerusalem is a beautiful town However it is full of conflict. There is always somebody crazy who hates the American and wants to hurt them, so better to avoid taking chances. The best thing to do in Jerusalem Visiting Hezekiah Tunnel , The museum and of course where Jesus walked , prayed and died. So two days is ok but if you can have more time will be better. I love the old Town market and I love shopping there for Herbs & spices.They have the best. If you have more questions email me .

в Иерусалиме есть замечательные гиды русскоговорящие. Я очень люблю изучать город с Зоар Хальфан, ее страничка есть в ФБ. Есть еще Вадим Лаут, Юлия Хович. Ну еще много талантливых гидов есть. Это если самим ехать и потом на экскурсии попадать, чтоб знающие люди вас везде поводили и показали. А можно и в турагенствах экскурсии заказывать, и самим бродить - в интернете обо всем масса информации есть и карты соответствующие.

в связи с тем, что въезжающие как туристы стали массово оставаться и работать нелегально, ужесточился безвизовый въезд. Причем проверка может занять как 15 минут, так и 7 часов, а многих заворачивают, не объясняя причин - право принимающей стороны. Проверяют и наличие обратного билета, и гостиничную бронь, и знание адреса, куда направляетесь. Проверяют психическую стабильность, задав вопрос и оставив вас одних (камеры наблюдения включены, но не заметны) в комнате досмотра. Потом может зайти другой сотрудник, начать задавать те же вопросы. А психологи в это время изучают вашу реакцию и выносят вердикт: адекватен ли турист, не представляет ли социальную угрозу. Поэтому: улыбайтесь, господа! ( ну и соответствующими документами обеспечьте себя)

Проблем не было. Доступ был открыт для всех. В одежде требуется соблюсти сдержанный и достойный вид:ничего открытого, короткого, мини. Желательно иметь головной убор или платок.

I don't think it will be closed in this days because the Holy Sepulcre Church (christian place) and the Temple Mount (muslim place) are not jewish places to the Jewish New Year.

Both places require quite alot of walking! My phone data tells me that we did about 6miles each day minimum! It could be more as well! Depending on how many places u plan to visit. Wear Comfortable shoes!! Especially in Jerusalem, there are cobbled streets and they're quite uneven!!
