While many locals opt for bikes, Copenhagen does have a fairly extensive and efficient bus network. It can be troublesome, though, for visitors to figure out what line to take to their destination as there is little in the way of network maps available at bus stops and schedules rarely include the entire route. This is where our Copenhagen Cards came to the fore because we could just jump on and see if the bus was going in the general direction we wanted. If it turned, we jumped off and tried another bus.
There are several types of bus available: regular buses are simply denoted by their number (eg. 10). A buses (eg. A2) are the backbone of the city's bus network which consists of six different lines with frequent departures and stops. During the day time there are no schedules as buses depart every two to six minutes. Many stops do have a small electronic display showing how many minutes are left until the next bus arrives. S buses (eg. 300S) are long express services with few stops and extend far into the suburbs, usually across the radial suburban train network or along corridors with no rail service. They can also be useful between points in the centre as they are faster than other lines.
E buses (eg. 173E) are express rush-hour services of little use to visitors as they mainly service commuters. One exception is line 20E which runs between the central square Kongens Nytorv and the DFDS (Oslo/Szczecin ferries) and cruise terminals. N buses are a network of ten bus lines operating at night between 1AM-5AM daily, when normal traffic is halted, and they are much more frequent at weekends.
The only bus map that we saw in Copenhagen was the one in the Copenhagen Card booklet. This was a good map and showed how bus routes connected with the rail network but frankly if your stay in the city is only for a few days it is probably not worth your while to try to understand the system.
There is a variety of bus serving each route. Some are normal single buses, others are long articulated vehicles and there are also some double-decker units
