North towards Gdańsk
Take the bus towards the Real supermarket. Close to this hypermarket, there is bus stop which is a cool place. There is a free bus service. You can find the bus stops on the Odrodzenia Street (near theater square).
South towards Lodz
All you have to do is just take any bus to Czerniewice for example bus number #11 or #38 (end of the city). When you will see wood it is time to get out :).
South-East towards Warszawa
Take the bus toward Carrefour supermarket. Close to this hypermarket, there is bus stop which is a cool place. There is a free bus service. You can find the bus stops on the Odrodzenia Street (near theater square). But you must be careful! One direction is going to Warszawa and the second is going to Olsztyn!
n0id believes that this warning refers to the split of the roads close to the supermarket. Make sure to be on Szosa Lubicka and you are on the right way to Warsaw.
Another option is to take Tram #1 or #4 in direction of Olimpijska to the final station. This might be easier than taking the free bus, because there are several tram stops close to the center. When you exit you'll see a lot of wood around and a residential area to the north. Cross it and after a few hundred meters you will reach the Szosa Lubicka. Turn right and directly after the traffic light you can find a bus stop which is a good spot to hitch from.
According to the polish site autostopem.net you can also take the busses #22 or #31 to the final station to reach the above mentioned Szosa Lubicka or the Carrefour supermarket.
West towards Bydgoszcz
Take the train number #1 to Merinotex and go to the end of this train.
South-West towards Poznan
Take bus number #10 or #20 to one of the stations at the Pozńanska street. Take care, because bus #10 turns right after the bus stop Stepowa. Bus #20 goes even further along Gniewkowska street. n0id didn't manage to try it out, so find out yourself which of the bus stops seems most suitable for hitchhiking. Have a look at googlemaps and the MZK website (see below) to know approximately where you should get out.
You can find the schedules of all busses and trams on the website of the public transport service MZK. There is even an english version of the schedules avaible with informations like ticket prices, an explanation of how to use the timetables and maps showing where the different tram and buss lines run. If possible check your choosen connection beforehand to make sure you know where you are going and how to get there, as the stops are lacking maps and sometimes even timetables.
