Köln-Bonn

1Terminal 1

On top of Terminals 1B and 1C special viewing areas exist. From the area on top of terminal 1B, you have an overview of all the runways, the military platforms and the WDL hangar (both on the west side of the airfield), but photography is limited here to the adjacent platform. Terminal 1C is the best place for landings on runway 13L. It is possible to take photos here, while the eastern cargo ramps can also be seen from here, as well as runway 06/24. On an irregular basis both viewing areas are closed though, at which point a stairways inside the terminal to a conference center (from "CaféBistro Leysieffer" up) may be useful.
Inside terminal 1C, on the route to terminal 2, fishrestaurant "Gosch" has a large window which gives an overview of the eastern platforms and runway 13L/31R.

2Runway 13L pm

This spot can be reached by walking from the terminal towards the construction site for the ICE train. This is a good spot for taking pictures of aircraft landing on runway 13L in the afternoon, although they are still high in the air. Following the footpath next to the fence eventually brings you to spot 3 and 4 as well.

3Runway 13L am

Leaving the terminal towards the A59, you take the first exit again (Porz/Grengel). At the second traffic lights, you turn right and after some 300 meters -at the next traffic lights- right again onto the Alte Kölnerstrasse. After a turn to the right there are parking places on the left side of the road, with a footpath towards the fence. This is a good spot to take pictures of the landing aircraft in the morning, when runway 13L is in use.

4Wahner Heide

A bit further south there is another footpath towards the fence, which will get you opposite the point where aircraft turn on the runway for taking off from runway 13L.

5Runway 24

When you keep on driving on the Alte Kölnerstrasse, you will cross the landing for runway 24. Although this is a suitable spot to collect numbers and photograph landings, the better option is just around the corner - provided you bring steps for photography. Continue past the approach lights and park where the road bends left. Walk along the fence to the runwway for a combined view on both commonly used runways, the cargo stands where most heavies park and part of the military area. Good for photos on 24 almost all day, and 13R/31L in the morning.

6Kriegerstrasse

Taking exit Porz/Grengel again, you now go to the left at the second traffic lights, towards Grengel/Wahn, which is the Grengeler Mauspfad. After some 350 meters you turn left again; there is a small sign "Kaserne" there. After 200m turn right again, into the Kriegerstrasse. About halfway you have a limited view on the western cargo platforms; with a good binoculair you can read some of the aircraft there.
At the end of the road you will find the main entrance to the military area, with right behind it the preserved Fiat G-91.

7Weststrasse

Following the Grengeler Mauspfad again, this will continue into the Weststrasse. Here you drive along the fence of the military airbase. When you look through the trees and buildings both the FIAT and F-104 "BB+374" are visible.

8South side

Continuing on the Weststrasse, after about 1.5km there is a turn to the left with a sign "DLR" (Deutsches Zentrum für Luft- und Raumfahr)]. This is the Flughavenstrasse. After some 600m -you already passed a second military gate- there is a small parking lot at your right hand side. When you park your car here and walk along the footpath to the left of the lake, you will get behind the military platform on the south side of the airport. This might be useful when something is parked here which could not be read off from the terminal. Photography is not possible here, though.

9Runway 31R

Walking to the south from the parking place, you will find a footpath crossing the grassfield. Follow this path towards the fence and you will reach a small mound. Standing on this mound you can make good pictures of the landing aircraft during the morning, on the rare occasions that runway 31R is in use. You have a limited view of the airfield here, though.

10Threshold 31R

Some 400 metres down the fence from spot 9, you reach a clearing in the woods near the end of the runway. During the morning this is a good spot for photography for aircraft lining up on runway 31R.
