There is no departure tax. Train and bus fares from some European destinations can be as expensive as discounted air fares, unless you have some kind of transport pass. Road connections with Poland are good and getting better, but there are still border delays, especially when crossing from other eastern European countries. Many border crossings to Germany and the Czech Republic have been closed since terrible floods in July 1997 damaged bridges. There are sea connections from the UK and Scandinavia to Gdansk, Gdynia and Swinoujscie.
Most services have car-freighting facilities.
Getting Around Forget about flying within Poland unless you're trying to launder money. The trains are pretty good and where they don't go the buses do. As well as the plodding government service, private bus companies undercut each other viciously on many intercity routes. Fill up your tank every time you see a petrol station and carry some spare thingummy ratchets and dooveywacker belts otherwise you'll be waiting around a couple of weeks for them to arrive from Germany. Rural Poland is quite conducive to cycle touring, being mostly flat and relatively quiet, but the urban areas are bike-unfriendly with few dedicated paths and many hostile motorists.
