In the next few years I plan on taking a trip to Strasbourg. While there I would love to hop across the border and catch a Bundesliga game. Logistically, which club(s) would be best to see from an ease of travel and time perspective? Thanks in advance for any advice!
Freiburg is an hour, Stuttgart an 1hr 15, Hoffenheim is 1 1/2 hours, and Kaiserslautern (my suggestion) is less than 2.
Kaiserslautern's stadium is on a hill right above the train station, but at a minimum you would have to change trains in Manheim. No clue about Stuttgart or Freiburg. I am pretty sure that Hoffenheim's stadium is nowhere near a train. Walking up the hill game day in Kaiserslautern is something everyone should experience. You can hear the stadium all the way up, but cannot see it until you get on top. The ground shakes.
Karlsruhe is in the 2. league (maybe 1. next year), little over half an hour by train from Strasbourg. Like the others said, Freiburg and Stuttgart would be relatively easy to get to as well but bit longer travel.
