By tram and bus
Ticket for one ride Einzelbillette is CHF4.00; daily pass Tageskarte is CHF12 2008. The city used to provide a "Berncard", an integrated ticket good for unlimited rides on all modes of transport within the city and the surrounding area including the Gurtenbahn funicular to the top of the Gurten hill - see below as well as free or discounted admission to many of the museums and attractions for the price of CHF20/31/38 for 24/48/72 hours from the moment of validation. As of October 2009, the card is not offered anymore.

Operator of the local tram and bus services, and provides timetables and other information on its web site or by telephone.
By rail
Berne's S-Bahn rail system will take you to many places in the suburbs and even to other nearby cities like Biel, Thun, Fribourg or Solothurn.
Berne has an excellent public transportation system, with frequent local city services provided by trams, trolleybuses and buses, together with an S-Bahn rail system for longer journeys into the surrounding suburbs.
By bike
You can get a free bike for four hours at "Hirschengraben". All you need is an ID and 20 CHF for deposit, and you can explore Berne by bike. After four hours, you'll have to pay 1CHF each hour. The "Hirschengraben" is less than five minutes away from the main train station. It's a stop for trams. Ask somebody, it's easy to find!
On foot
The city center of Berne is easily accessible by foot. You can get around the main shopping area and restaurants simply by walking. But if you are going to go outside of the city center in areas like Guisanplatz, it's better to go by tram unless you want to be walking for 45 minutes.
By car
As in most Swiss cities, free parking space is rare and the paying ones in the city center are quite expensive. As the center is quite small and all of the major attractions are within a mile walking distance it's a good choice to park in a "park and ride" and take public transport to the center of town.
