Much of the center and historic areas are easily navigable on foot. If you’re looking for an easy way to get around, a pair of walking shoes is your best bet. Bolt is Budapest's answer to Uber or Lyft, and they have an easy-to-use Android and iOS app. The public transport system is comprehensive too; trams traverse most of the city for as little as €1 and EU residents over 65 benefit from free public transport. Be aware that, except for night buses, tickets must be bought before boarding. They can be bought at Metro stations, vending machines at some bus stops, or at newsagents. Ticket inspectors can be anywhere – best to stay on the right side of the law!
