Most Polish cities have well-developed networks of public transport. Depending on the city, they include buses, trams, trolleybuses, trains, and underground trains. It is usually a good idea to buy a long term ticket, as it's hard to avoid public transport.

Public transport in Poland is widely considered to be excellent, especially in its major metropolitan areas. Cities like Warsaw, Kraków, and Wrocław feature highly integrated networks of trams, buses, and increasingly expanded metro lines that are punctual, affordable, and clean. In 2026, the system has become even more robust with the introduction of "Clean Transport Zones" that prioritize electric buses and tramway expansion. For intercity travel, the national rail operator PKP Intercity offers modern Pendolino high-speed trains that connect the largest cities comfortably. Most passengers use mobile apps like Jakdojade or Koleo to plan trips and buy digital tickets seamlessly. While rural accessibility remains a challenge compared to urban centers, the overall infrastructure is among the best in Central Europe, offering a reliable and cost-effective alternative to driving for both residents and international visitors.
