Bydgoszcz is reachable by road from all major cities but as with much of Poland the roads are either in poor repair or undergoing a huge rebuilding/expansion program. From whichever direction you approach the city, you should keep your eyes peeled for 'centrum' signs. This will bring you into the area around the Rynek or New Opera buildings. From there it is a bit of a lottery finding your way into the very central area. Keep your eyes peeled for signs for 'Rynek'. There is parking in the central area but you will need to buy a ticket at one of the machines. Guarded parking is available and some hotels also offer this service to guests.
