The city center is small and easy to get around on foot or by bicycle. Rent a bike from the Styr & Ställ stations all over the city. It’s 25 Swedish kronor (less than $3) for a three-day pass that gets you unlimited 30-minute rides (a ride lasting longer than 30 minutes incurs small fees that depend on duration). Just be sure to use the cycle lanes: There is a well-developed network that takes you almost anywhere. Trams, buses, and boats are all part of the public transport system and you can use the same type of ticket and pass to ride them all. This even applies to buses leaving Gothenburg, if you want to go on an excursion out of town. One-day tickets are 90 kronor and a single ride is 29 kr.
