Let’s just say that you have a day in Frankfurt. Or at least 8-10 hours of connecting flight in the city. If you are boarding on a Lufthansa Airline flight, there is a huge chance you will be transferred at/from Frankfurt am Main Airport. Don’t fret – the airport is well-connected with trains to downtown Frankfurt.
Once you arrive at the city’s main train station, everything there is walkable, assuming you have well-shaped calves like mine (aka, someone who likes walking for hours).
So, if you have a day in Frankfurt, here are my suggestions – starting from the main train station. Take note that this travel itinerary of Frankfurt does not include recommendations for restaurants and bars because you can always go into one – anywhere in the city. Also, museums and galleries are not included here.
