I spent a record seven nights in Cologne because I was waiting for my friend to get a flight to Barcelona where we will meet on Sunday. I got a flight from Frankfurt to Barcelona so I have time to make a few more stops in Germany and Luxembourg.
After an early breakfast at the hotel, I packed up and checked out and walked the one kilometer to the train station and bought a ticket to Koblenz. In Koblenz I changed trains to go to Trier, Germany which is close to Luxembourg. I had to leave a little early because the reception at the hotel I booked in Trier is closed from 14:30 TO 18:30 so I need to get there before then.
The Koblenz train was standing room only in 2nd class so I sat in the dining car and had an expensive coffee. The trip to Koblenz was about an hour.
In Koblenz I only had to wait about 10 minutes for the next train to Trier. I bought a ticket to Trier, and hopped on the next train. They checked tickets on the train to Koblenz but not the train to Trier. That was the first time that my train ticket has been checked in Germany after numerous, mostly short train trips.
The train followed the river through the Mossel River valley which is hilly wine country and very picturesque with little villages and a few castles high on the hilltops.
Trier is famous for several reasons. It is the birthplace of Karl Marx, the father of communism. It was also an important Roman city so there are some interesting ruins such as the Porta Nigra Roman gate, some baths, and an amphitheater. Lastly, it has a charming old town elaborately decorated buildings and a massive cathedral.
