Scandinavia: Denmark, Sweden, Norway » Aarhus and Moesgaard
My conference was in Aarhus (Denmark), a three hour train ride from Copenhagen. During a free afternoon, I walked to the Moesgaard museum --- a ten mile round trip. Lonely Planet got this wrong and said it was a five mile round trip; no wonder the hotel receptionist looked surprised when we said we were walking there. The highlight of the museum is the Graubelle Man, a 2000 year old corpse preserved amazingly well in a bog. I also went walking around Den Gamle By (reconstructed old town) in Aarhus but that was pretty disappointing. Fortunately, I went after closing hours when there was no entrance fee to walk around.
