Travel questions? See Good to know in the travel guide below.
Cologne in late November is damp, mild for the season, and centred entirely on its cathedral, which is visible from most of the city. A four-day .NET conference here benefits from a compact centre where venue, hotels and the old town sit within walking distance of one another. The Rhineland's noticeably sociable culture makes the evening programme easy to extend.
Cologne Bonn Airport (CGN) connects to the main station by S-Bahn in about fifteen minutes, which is unusually quick for a European airport transfer. Dusseldorf (DUS) and Frankfurt (FRA) are also viable, each around an hour by direct ICE train. Cologne Hauptbahnhof sits directly beside the cathedral and is a major national rail junction, making arrival by train straightforward from most of Germany.
Skip the taxi queue — pre-book a fixed-price airport transfer with Kiwitaxi. Exploring beyond the city? compare rental cars on Auto Europe.
German mobile coverage is strong in the city but roaming outside the EU is costly. An eSIM activated before travel keeps things simple. Set up an eSIM with Airalo before you board and you're online the moment you land.
Cologne Cathedral. A Gothic cathedral of genuinely overwhelming scale, six centuries in the building and directly adjoining the main station. Entry to the nave is free; the tower climb is 533 steps and worth it on a clear day. Allow an hour, or two with the treasury.
Cologne Christmas Markets. Several distinct markets run across the centre from late November, with the cathedral market the largest and a smaller harbour market at Chocolate Museum quay. Gluhwein and roasted nuts are the standard order. Evenings are busiest; late afternoon offers a better balance.
Museum Ludwig. A first-rate collection of twentieth-century art, with major Picasso and Pop Art holdings and one of Europe's strongest photography collections. Situated immediately behind the cathedral. Two hours covers the highlights comfortably, and it is an obvious wet-weather choice. Tickets on Tiqets →
Rhine Riverside Walk. The promenade along the left bank gives the best perspective on the cathedral and the Hohenzollern railway bridge with its accumulated padlocks. Cross the bridge on foot for the return view. Forty-five minutes at an easy pace, ideally around sunset.
How long is the airport transfer?
Cologne Bonn Airport connects to the main station by S-Bahn in roughly fifteen minutes, making it one of the quicker transfers in Germany.
Are the Christmas markets open during the conference?
Yes. Cologne's markets typically open in the final week of November and run through December.
Is English widely spoken?
In hotels, restaurants and the conference environment, generally yes. Some smaller neighbourhood establishments will be German-only.
