About Frankfurt
Frankfurt is Germany's banking capital — think glass skyscrapers, not medieval charm. Most people just connect through here, but if you've got a day, the Römerberg old town survived WWII, Sachsenhausen has killer apple wine taverns, and the Main River walk is surprisingly pleasant. It's a gateway city, not a destination.
- •Römerberg square for the old-town vibe
- •Sachsenhausen apple wine taverns (Apfelwein is Frankfurt's thing)
- •Museumsufer (Museum Embankment) along the Main River
- •Palmengarten botanical gardens if you have time
