Can someone tell us the best way to get from Luxembourg Airport to Trier in the late afternoon on a Monday? We're starting there for our Rick Steve's tour! Thank you.
When I went 5 years ago I used the city bus to the train station then the train to Trier. It looks like there may a direct bus option from the airport.
