By train. Just go on www.pkp.pl,click on the English button and type in the locations and date. It'll show you the available connections and price. Remember,if you don't know any Polish try as well as you can to get a connection that goes directly to your desinations,without having to change trains - it's hard to do it as a Polish person,even more so for a foreigner (it is admittable that the train station in Wroc?aw looks fantastic now and is visitor-friendly,but other cities might not be). If you have any trouble boarding a train and aren't sure whether it's the right one or not (the smart thing to do is check),ask the conductor or someone that's getting on it - ''Witam,czy to jest poci?g do... *desination*'' (Hello,is this the train to... - pronounce as ''Veetam (''a'' as in ''acapella''),chi (''i'' like in ''ick'') to (''o'' like in ''ornament'') yest pochong do (''o'' as in ''ornament'') ...) Polish is a hard language to learn,but knowing just the basics like ''Dzie? dobry'' (hello - jen dobri (''i'' like in ''ick'') and ''dzi?kuj?'' (thank you - jenkooyeh) can help you a lot. Good luck in your travels!
