We are trying to avoid going through Strasbourg airport to drop off the car. We will be coming from Colmar. I see that it is possible to drop off the car on the French side of Basel.
We will then need a train from Basel to get to Heidelberg. Would you suggest train to Mannheim then change to train for Heidelberg? We don’t want a car, so will be using public transport.
Any suggestions would be greatly appreciated.
