The bike tour that i went on was awesome!!! It was well worth the money, it was a 5hr tour which covered around 9km all up. i went to Bradenburg gate, Checkpoint Charlie, The Berlin Wall, Hitler's Bunker, Victory Column, Postdamer Platz, Nazi Topography of Terror, Gendarmenmarkt. Reichstag, Book Burning (Bebelplatz) Deathstrip and watchtower, Natzi Luftwaffe ministry, Soviet War Memorial, DDR Palast der Republik and Musem Island, i saw a lot more as well while i wasn't on the tour but it was an amazing experience!! My butt was very very sore though!! I then watched aus play with a bunch of aussies in the hostel, the atmosphere was great.. it was an excellent and exciting game. I went to Sanchenhausen Concentration Camp in It was very very depressing, i hired an audio guide and followed the map there were 37 different area's to look at , and the audio guide was like if you were walking as one of them, it was pretty horrible, very interesting though but still, and well worth it. I walked around for the 4hrs and my legs were pretty tired, and i was emotionally exhausted. I went to bed early that night as i was leaving for Dublin the next morning... will write another one soon about Dublin first day... :)
