Trier, Monschau and Aachen
I finished the trip, by visiting Trier, Monschau and Aachen.
Trier is the city with the magnificent Roman gateway, Monschau is a picture postcard village and Aachen is famous for the cathedral.
What surprised me was that I was there in July and Monschau was absolutely dead and I had great difficulty finding a hotel that was open. I would have thought that it would have had more visitors.
