Upon arrival in Barcelona I had about 6 hours to kill before my friend was able to meet me. I took the train from the airport into the city center (about 20 minutes), changing trains once to make it there. It was recommended I get off at the Estacio de Franca stop where there is a beautiful building and access to a park and the sea side. I wandered around a bit and, to my surprise, stumbled upon the Barcelona Zoo! I gladly paid the 16 euro entrance fee and spent the rest of the afternoon watching the animals and watching people. I was enthralled by these animals, and even teared up a bit when I watched a few.
