Parc Guell - Gaudi's park in Barcelona.
It was pretty awesome. I would highly recommend it to anyone visiting Barcelona. Even better, catch the train to Joanic and then the 116 bus. You won't have to walk up the hill that way. Plus a really awesome Nana told us where to get off... although the trippy garden also kinda gave it away.
Oh and the cute as ginger kitten at the beginning is called Kenny. He lived with us in Barcelona.
