We only had one day in Athens before heading to the Islands, so we wanted to make the most of our day by going to the Acropolis. The Acropolis was built on top of a small rocky mountain top, our concierge explained to us where we could catch the bus to the top, but then quickly mentioned that there is a walking path that you could also take to the top.  We of course decided to take the challenge to walk it ourselves, without realizing that it was going to be a very humid 100 degree day.
