I'll be coming to Poland towards the end of October for 6 weeks. I was hoping to visit Prague during the weekend. Can anyone tell me the best and the most inexpensive method of travel? Also, how much will it cost?
From Wrocław you have a bus of polskibus.com. They are cheap and quite comfortable.
To Wrocław from Rzeszów you will for the best get by bus (check at e-podroznik.pl) cause there are no direct trains.
Alternatively by train with changing a vehicle in Katowice or Kraków (check at rozklad.sitkol.pl), but then you should buy tickets with reduced price in advance:
intercity.pl/en/site/ec-en-m/special-offers/journey-to-the-czech-republic-from-24-%E2%82%AC.html due to the fact that normal international tickets are very expensive.
More complicated and rather hard for not speaking Polish person, but even more cheaper way (only for "green" trains in web timetable, not for "blue" ones) is to buy in Poland a ticket to the national border (the ladies selling tickets often refuse to sell a ticket not to a station, but to a border point) and the next ticket to Prague from a Czech conductor.
