Scant information exists on the Ramparts Walk around the perimeter of the Old City of Jerusalem. One of the most popular tourist sites in Jerusalem, the Old City is filled with exotic smells, flavors, and history. The Ramparts Walk is a way to see the Old City and the new city from a high vantage point. You can start at multiple locations, though the easiest to find is at Jaffa Gate.
Entrance fee is NIS16 for and adult and NIS8 for a child (at least 8 years old is recommended) and the hours are 8am-4pm Sun.-Thurs., though you can enter right before 4pm and still get out at your leisure.
Just to the right of the entrance to Jaffa Gate is a small sign with an arrow:
Follow that alongside the outer wall of the city until you reach a tiny metal gate and a staffer who will take your money.
If you come at the end of the day just before closing, your ticket is good for the following day. Taking the Ramparts Walk about 1 hour before sunset is an incredible way to see east and west Jerusalem. Really sturdy shoes are a must. There are railings, but take your time and don’t rush as the stones can be uneven and slippery at times.
All along the way there are historical markers with explanations of the area. You can descend at several different points, though the closest from Jaffa Gate is about 25 minutes.
