Cardiff is about as compact a city as you’re going to get in the UK, meaning everything is easily accessible by foot or on two wheels. If you’re feeling a little lazy, there is also a good network of public transport around the city. A single ticket on the bus costs £1.90, but you might as well get yourself a ‘day-to-go’ ticket, which costs £3.90 from the driver and lets you jump on and off as much as you like.
