On our second full day in Frankfurt, we took a day trip up to Cologne. The main part of the excursion was tour through the city on the upper deck of a tourist hop-on hop-off bus (we couldn't get off). This was a "quick" way to see the city but didn't allow for a lot of photographic opportunities since the bus never stopped in one place.
After that, we went inside the amazing Cologne Cathedral for a little while before heading back down the Autobahn to Frankfurt.
