This is a stunning site - not just for the scale but for all the detail inside.

One of the first things that hits you about Cologne Cathedral is its location. It's literally right outside the main train station and it's the first thing you see when you arrive by train.

I stayed in Cologne for a few days and used it as a base to see a few other WHS, but it's worth noting that you could see the cathedral on your way somewhere else because of the ease of access from the station.

It's possible to climb one of the spires and I highly recommend doing that. It's not just for the view (which is great) but you get to see some of the architecture close up and get a sense of the scale of this building.

Inside the cathedral, there is so much to see. I walked around and saw it independently but, in hindsight, I wish I had done some kind of guided tour to learn about everything that there is.
