The only direct way to Krakow from Prague is via night train. It actually wasn't too terrible, because I was with my friends, and we got our own compartment. The train left at 9:30pm and we got into Krakow a little before 7am. The town was small, so it was only about a 10-15 minute walk to the hostel. We spread out and took naps on the lobby couches before we headed out. First stop: perogi place. I had cottage cheese and potato boiled perogis:

We had decided that we were going to tackle Auschwitz that day, so after that we walked around a little bit, and then went to meet the bus in some kind of memorial square (couldn't find any information about its significance, but it was really pretty!):

The bus to Auschwitz took a little less than two hours, during which time they showed a documentary about the camp with lots of actual pictures. I hadn't even seen all of the things featured in the movie, so I was glad to have seen it. We learned that Auschwitz was actually composed of multiple parts, with a sister camp, Birkenau, about a five minute drive away. Right after the liberation of the camp, all of the actual barracks of Auschwitz were cleaned out and made into museums, so none of those are actually still in existence for people to see, but each barrack is a different exhibit (some confiscated goods, some focusing on different parts of the camp's history, etc.), and we went into most of them on the tour.
It was an absolutely gorgeous day, which made our visit even more painful, in a way. It was very strange to emerge from dark, emotion-evoking buildings learning about a very tragic history into one of the most beautiful days of the whole semester. Our tour guide spoke into a microphone and we all had headphones to hear what she was saying, which was great because we could kind of wander and see things for ourselves. It was a very individual experience, yet when I looked at my friends I could guess that their facial expressions at hearing the horrors of history were probably very similar to mine. It is shocking to think that humans are capable of doing such things to fellow humans. I have learned so much about Auschwitz, seen so many pictures, read so many books and articles, but actually going there and seeing it and taking the wonderful tour they provide was a complete experience unto itself. No movie or article can hit home as hard as seeing piles and piles of suitcases, or shoes (and they had a whole case of baby shoes), or especially real human hair. Walking through a gas chamber and emerging on the other side is a strange and unforgettable event. We decided that everyone should go through the experience of Auschwitz once in his/her life. Here is a picture of Auschwitz and a picture of Birkenau, and I am posting my whole album of pictures from the day if you want to see more:


We took our hour and 40 minute bus ride back to Krakow, and decided to have dinner at a Georgian restaurant (the country, not the state!) We then hung out at the hostel for a bit, and went out to a disco with multiple floors that played old and new music (even heard some Lady Gaga, which means that Krakow music is more advanced than Prague's!)
The next day, we slept in and then went to lunch at a Mexican place. It wasn't too bad for Krakow! The main attraction in the city is the Main Market Square, which has this clock tower:

There was a flea market going on, so we walked around the square for a while before exploring some more parts of Krakow. We went to the Wawel Castle, another famed attraction:

It had a nice view from the top and everything, but it definitely isn't the Prague Castle! There was a fair going on near the castle, which had Polish food including, of course, the famed Krakow staple cotton candy. It also had ballooons, music, and rides. We felt like we were back in America!
After the fair, we headed over to Kazimierz, the Krakow Jewish quarter. There are currently only about 200 Jews in Krakow, but there are 6 synagogues and lots of Jewish restaurants and museums and things still around. I dragged my friends through the entire quarter! Just to give you an idea, here's a route similar to the one we took:

After that we walked back to the hostel, relaxed for a while, and then went to an amazing Polish restaurant recommended by the guidebook my parents gave me for Hanukkah (which we used on practically every trip...well done, parents!) We took another night train back, and arrived in Prague around 7am.
Overall, the trip to Poland worked out perfectly. We didn't really need that much time there, so it was perfect to just go for two days, but it was extremely meaningful to go to Auschwitz, and interesting to see Krakow to round out the Central European experience.
