This fantastic Scottish owned bus company operates an express line connecting Prague and Warsaw, with stops in Wrocław and Łódź, and is definitely the best, cheapest way to travel between those cities. All buses are comfortable and wifi-enabled, and if you book ahead your fare could be as low as 1zł. As good as it gets by bus and our only complaint is that they don't provide a service to Kraków.

Buses bound for Prague depart daily from Dworzec Centralny at 14:20 and 01:20 in the morning, with a travel time of just under five hours. Express buses to Warsaw leave at 06:00, 10:00 and 16:00 with a journey time of only six hours. 13:40 and 01:40 departures stop in Łódź en route (journey time 4.5 hours) before arriving in the capital at 20:55 and 09:00 respectively.
