Essential when you take the bus, bus boat, train, S-Tog or subway: the right ticket.
Be careful here, you don't have to pass any door, so you may well get on a train without even thinking about tickets... (at least in a bus, the driver would stop you). Beware not to try it though, you would soon discover the 600 kr. fine the not convincing enough "I am a tourist, I didn't know, I am sorry" excuse would get you....
For occasional travelers who do not have a monthly card, never forget to "klipp" a ticket (klippekort) in one of the yellow composter.
Above the composter, a map shows the number of areas needed for your trip. For example inside Copenhagen, you stay in the red area, so you only need a 2 klipp ticket. To go from Copenhagen to Hillerød (to see the amazing Frederiksborg castle), it goes up to nine zone (or all zones) Then, everything is modular. To do that 9 zones trip, you can make a klip on a all zone card (the cheapest option) or one on a "5 zones" + one on a 4 zones, or three on a card "three zones", etc...
When you always want to get the best price, you quickly get addicted to collecting colors!
This is clairly one of the most complicated ticketing system I have ever seen...!
Note: with the card on the right, you have to klipp once to travel with a bike. They really thought of everything ...
The advantages of these cards: they are cheaper than single tickets and can travel in a party (multiply the number of klipp by the number of passengers). Bon voyage!
