When coming to the water tunnels, you have 2 choices; the Caanite tunnel (which is narrow but dry), and the Hezekiah Tunnel which has flowing water and a storied history.
Our tour group decided to do the dry tunnel, I had to go back the next day for the Hezekiah tunnel. The story goes that 2 teams were digging from opposite ends and met in the middle, to provide a water system for the Jerusalem city.
Who should go, what will you experience?
1. I am 5'7" and the deepest water was to my knees. Most of the time it was high ankle level. Must wear water shoes and bring a flashlight or headlamp. The headlamp worked well for me.
2. I had to stoop over about 1/3 of the way. It may be uncomfortable for a tall person
3. Width - it was narrow, but never to the point where I needed to sideways.
4. The tunnel emptied at the Pool of Siloam
How to return after exiting the tunnel?
Per the suggestion of the security guard, I returned through the Roman Sewer Tunnel. Do not be alarmed, this is a relatively dry tunnel. You need to be able to make many steps up, over rocks and on sand bags. It was narrow and a little stuffy but it was a good experience.
I exited this tunnel at the new excavation site across the street from the City of David
I highly recommend these hikes, if you are okay with walking, narrow spaces, and can do many steps. The history alone makes it a great memory of the trip.
