Today’s our last day in Vienna. Tomorrow we have breakfast and head to the airport. I was incredibly exhausted today, but we trekked out to a small town outside of Vienna called Hinterbruhl. We took a tram, a train, and a bus to get there. It has a system of underground caves and a large underground lake called Seegrotte. It was incredibly cool, even if I was falling asleep half the time.

It was very cold down there, and this butterfly we made friends with outside hitched a ride in my hair. I had no idea she was there until we were well into the caves. She stayed with me almost the whole way, but when I came out she was gone. I hope she didn’t freeze down there.
