When the weather turns in Cologne
Schildergasse, among the busiest shopping streets in Europe, is sheltered enough to cross the city without opening anything. Better still is Claudius Therme in the Rheinpark, thermal pools looking back over the water toward the Dom. The Ludwig, the Wallraf-Richartz and the cathedral itself stand within four minutes of one another near the Hauptbahnhof, so a soaked afternoon absorbs all three.
Cologne's museums, and which one to pick
Museum Ludwig charges 13.50 euros, closes Mondays, and owns the third-largest Picasso holding anywhere plus a deep Pop Art floor; on the first Thursday of each month it runs until ten and drops to seven euros after five. Wallraf-Richartz covers the centuries Ludwig skips. Hardest and most necessary is the NS-Dokumentationszentrum, where prisoners' graffiti survives on the walls of the old Gestapo cells.
What to eat in Cologne
Kolsch arrives in a 0.2-litre Stange and the Kobes will keep replacing it unasked until you lay your beermat across the glass; that is the working rule at Fruh am Dom and at Paffgen. Order Halve Hahn expecting a rye roll with aged Gouda rather than half a chicken. Himmel un Aad is blood sausage with apple and mash. Neither is optional in a Brauhaus.
What first-timers get wrong in Cologne
In a Brauhaus the Kobes tallies your drinks in pencil strokes on the beermat and frequently wants cash at the end, so do not assume a card reader exists. Never order Alt here; that is Dusseldorf's beer and the rivalry is old and unamused. Validate KVB tickets in the onboard stamper. Arriving during Carnival week means tripled room rates and a largely shut city.
What things cost in Cologne
A 0.2-litre Kolsch costs between 2.20 and 2.90 in a Brauhaus, which explains why the glasses keep arriving; a Halve Hahn is around six euros and a full Brauhaus plate fourteen to eighteen. The cathedral is free and its tower eight euros, Museum Ludwig 13.50. A single KVB ride inside the city zone runs a little over three euros, a 24-hour ticket about nine.
