Frankfurt is one of the world’s busiest airports, yet they still think of the enthusiast and people who are interested in how an airport runs.
Their airside tours have been running for many, many years. They used to operate from the Terminal 1 viewing deck (remember the DC-8 nose section where the tour started? It’s still there by the way).
Today, you can still take a tour at one of the set times between 11am and 4pm. It costs €8 for adults and lasts around 45 minutes. It will take you on a bus tour of airside areas, including Terminal 1, Terminal 2, maintenance areas and taxiways.
To take the tour, head for the Frankfurt Airport Centre in the corridor between Terminals 1 and 2. Follow signs for the Airport Experience Tour. Here’s the link to the official information page
