Enter the Tunnel via the lift or stairs down. Its over 2000 meters long to the other side of the river. Its only made for foot or bicycles. On the other side is amazing views of Hamburg Port. Would recommend taking the stairs down and the lift up.

A short and free experience, this is a walk & cycleway connecting both banks of the Elbe river via a tunnel underneath it. This was built early in the 20th century and is an impressive feat of engineering. To get down to the sub-terrain tunnel you can go via the stairs or lift, I recommend the former, as although narrow, it allows you view the massive towers at each end together with the impressive height and depth that these were built with. The view from the lift is more narrow. It's not a long ascent or decent and is quite manageable. Do be aware however it is a daily through route for many workers and city residence across both sides of the river, so be sure to watch for cyclists who use the centre of the tunnel, and other people wanting to use the stairs/lift. If travelling from Landungsbrucken to the southern side of the river, do not expect a lot to see from the other side. It is mostly all industrial land useage being near the Blom & Voss yards and other industrial estates nearby. There is a viewing point however, but again its not massively impressive. I do not consider this a must see attraction for Hamburg. They are doing some restoration works to the Alter Elbtunnel in 2023, which may been it is closed or restricted at periods - although Hamburg Port Authority (HPA) which is doing the works, tries to avoid this where possible.

I missed this walk-through on the last visit, so made sure to include it this time. I'm not sure I would recommend as a must-see, must-do. Interesting enough, but not overwhelming. Built in the era of some of the European subways, the ceramic tiles struck me as quite similar to older areas of London's system. We took the stairs down and elevator up, as others recommend. I would have been satisfied with elevator down, a short peak into the tunnel, foregoing the walk through, then elevator back up. But, live and learn! If you walk the tunnel, do take care of the bicycles that whizz by in the center of the tunnel. It is easy to step off the pedestrian way into their path as you maneuver around slow moving groups of walkers. Good enough for a rainy day, but I wouldn't go out of my way to make this an essential part of a Hamburg visit.

The tunnel is approx ½km long, and you have to walk there and back. There is a snack bar at the far end, but no toilets. Excellent views of the Landungsbrucke and Elbphilarmonie, but very few places to sit and admire the view, plus no shelter from the blazing sun it, more likely, the rain! Well worth the effort, but do beware of the lunatic cyclists riding in the tunnel at maybe 4x the 10kph speed limit, millimeters from you!!!!

What a fantastic place. Pristine and the early 20th century tiling is magnificent. Can't believe it is free to use TBH. The view back to Landungsbrueke from the far side is worthe seeing too, as well as learning about the pow forced labour in the dockyards during WWII. Not to be missed.

Really enjoyed our walk through the tunnel. Hard to imagine you are under the River Elbe. It was a rainy day , so great to keep you entertained while you keep dry. We just turned and walked back as ewe didn't see much to do at the other side.
