The best way to travel around the city is by public transport using a visitor pass (see last paragraph), alternatively, there are plenty of taxi's during the day and night, some will have fixed charges while others work on a meter, in rush hour the latter can cost more. If your travelling by car it is worth knowing that at times it can become extremely congested (3rd most congested city in the UK), avoid morning and evening rush hours as they can get bad, there are also new speed restrictions around the city centre. Public transport moves quicker along special bus lanes, there are also sightseeing tours and guided walks, these operate from Great Victoria Street, Royal Avenue and High Street. They are private operators so shop around or check-in for advice with the Belfast Welcome Centre.
