Hiring a car from Trier means you can venture into the rolling hills of the Mosel Wine Region; pleasant villages such as Ruwer are just 15 minutes away on the B49. If you choose to hire a car in Trier you'll also find Luxembourg City is less than 40 minutes away on the A1.
Historians will know that Karl Marx was born here and his former home has opened as a museum, but the city's symbol is probably the Porta Nigra, pointing to Trier's rich Roman heritage. You can drive up to St Mary's Column and survey the city, or explore the rolling hills of the wine valleys.
