I will be in Colmar and leaving the area from Basel Airport. After perusing several forums, it seems there are two main ways to get to Basel Airport from Colmar with public transportation. Would appreciate if someone can help confirm my understanding below. Thanks in advance!
1) First is to take the train from Colmar and get off at Basel SBB. From there, take #50 bus to Basel airport. Both rides can be paid in Euro. This seems pretty straightforward on Google map's direction. Any caveats I need to be aware of?
2) Alternatively, take the train from Colmar (same train as above) but get off at St. Louis instead. From there, take the #11 bus to airport. Both rides can be paid in Euro. Downside of this method is the bus does not run as frequently as #50. However according to Google maps, it is telling me to take the train from Colmar to Mulhouse, get off there to get on another train heading towards Basel SBB and get off at St. Louis, and from there walk to airport (no bus needed?). Can someone help me clarify what is the correct approach here?
3) I also see an option for Flixbus. Is anyone familiar with it?
