The Lahn-spring is located in the middle of Germany in the beautiful Rothaar Mountains. You spend the night directly at the spring in the middle of the forest in the cozy, comfortable “Forsthaus Lahnquelle".

Enjoy the first day of your trip in a particularly special way, because from a height of 600 m you roll down from the Rothaar Mountains through a forested landscape via Feudingen to Bad Laasphe. Along the still small Lahn, the well-signposted Lahn cycle path takes you to Biedenkopf, which is dominated by its Landgrave castle. Look forward to the romantic streets of the half-timbered old town on the Schlossberg and to the castle, which was built by Heinrich III in the middle of the 15th century. Today it is one of the most important cultural monuments of the State of Hesse.

You roll comfortably through the widening Lahn valley to Sarnau with it's Otto Ubbelohde museum. It is worth taking a short break here, because Otto Ubbelohde became known and famous for his drawn print templates for book illustrations and for his illustrations for the fairy tales of the Brothers Grimm. From here it will only take you a few kilometers to the old university town of Marburg. It is worth visiting the famous Elisabeth church and the Marburg Landgrave castle. Let yourself be captured by the fairytale old town and enjoy beautiful evenings in international restaurants or in rustic student pubs.

Time to say goodbye to the fascinating Marburg. But in the wide Lahn valley you roll quickly on flat paths to Gießen and can enjoy the journey through fields and meadows without any worries. The Mathematikum, the first mathematical interactive museum in the world, beckons in Gießen. Visitors of all ages and educational backgrounds can experiment here: they break their heads playing puzzle games, watch a ball race, stand in a giant soap skin and much more. Let yourself be surprised!

Today's trip is easy to cycle and takes you to Wetzlar in the morning without any effort. Explore the old town and the interesting cathedral on an extensive tour - it's worth it! Stroll through the medieval market square, discover steep stairs, narrow streets and romantic corners. Experience the modern side of Wetzlar on the optics course. Here you will discover optical phenomena, such as a large diamond made of optical glass, which reflects the light with a sparkle, or a kaleidoscope with infinite reflections.

The first kilometers of the day will be accomplished fast. You leave Wetzlar over the historic stone bridge and the route to Weilburg, whose renaissance castle lies on a high rocky ridge above the Lahn, remains unforgettable in terms of landscape. You can look forward to an informative guided tour of the palace, the beautiful palace garden with café and the only ship tunnel in Germany, which, completed in 1847, shortens a large, wide loop of the Lahn.

The course of the river winds it's way between Taunus and Westerwald today. You cycle idyllically on the paved path via Aumenau and Runkel to Limburg. The Limburg Cathedral, also known as St. George's Cathedral, towers above the old town next to Limburg Castle. This high location on the rocks above the Lahn ensures that the cathedral is visible from afar. It is considered to be one of the most beautiful creations of late romanesque architecture. Not only is a visit to the world-famous Limburg Cathedral an absolute must, but also a stroll through the city center, because it is one of the most beautiful old towns in Germany!

Enjoy another highlight today: away from any traffic, you roll along the Lahn cycle path through an untouched valley landscape from Diez to Balduinstein. But this day has two climbs in store, whereby you can comfortably bypass one ascent by train (11 km). On your way to Nassau, take a worthwhile break at the Arnstein monastery. A beautiful forest path leads you to Nassau with its small castle, which you can still conquer in the afternoon.

The historic inn on the Lahn beckons on the right-hand side of the Lahn before you cycle into Bad Ems. Be amazed by the numerous buildings that tell of the globally significant resort architecture (Bäderarchitektur), Roman history and German romanticism. Continue on by bike, after 12 km the Rhine Valley opens up before your eyes. What a wonderful view! You cycle on the beautiful Rhine cycle path to the Deutsches Eck and into the heart of Koblenz.
