The best traffic-free bike rides around Mückeln

A truly amazing experience for young and old. Turn on the lights – even though the tunnel is lit. And in hot weather, it's like riding through a "refrigerator."

A well-maintained cycle path runs around the maar, and beautiful views are guaranteed.

Very interesting and worth seeing place.

Worth a detour.

The fairy-tale fountain at the Alten Postplatz tells a story. Here, on this spot, it is at its most beautiful.

The Ulmen Maar lies 420 meters above sea level today, covers an area of 5.5 hectares, and is 36 meters deep. The bubbles at the maar's edge demonstrate that volcanism is still active. They bear witness to a turbulent past—but rest assured, there's no eruption in sight! A wall of various rocks and ash, up to 20 meters thick, surrounds the cone. For those interested, these testimonies to this explosive past are beautifully displayed in St. Matthias Church. This unique wall, with its different colored layers and rounded inclusions, is worth seeing for more than just geologists. The slopes of the maar basin are covered with a beautiful forest, which can be explored on a circular walk. A detour to the medieval castle ruins, from which the Crusaders once launched their campaigns, is recommended. The view from the crater rim over the maar and the Eifel beyond will take your breath away. Whether after a sweaty hike or a long drive, the blue of the Ulmer Eifel lake is all too tempting in summer. However, bathing in the maar is prohibited because it is designated as a nature and water protection area.

The lower castle has completely disappeared. You can still see the beginning of the ring that connected the lower castle and the Ulmen city wall, a two-story outer wall of the palace, as well as a cistern and some foundation walls of other buildings. The old part of Ulmen Castle was built around 1074 AD and likely rests on the remains of a Roman settlement. In the Middle Ages, Ulmen Castle was further expanded and divided into the upper castle, whose remains of the walls still exist, and the lower castle, which extended to the banks of the maar river. Two knightly families lived in the castle, which is believed to have never been attacked or destroyed until 1673 due to its size. Only the Sun King's troops succeeded. It was rebuilt, but fell again in 1689 during the War of the Succession. However, Ulmen Castle was also rebuilt this time, with only the city wall being abandoned. With the invasion of Napoleon's soldiers, Ulmen also became French and later Prussian. The empty castle, whose last descendant died in 1801, was auctioned to a merchant from Cochem, who sold it as a quarry. When a devastating fire burned Ulmen to the ground in the 19th century, the residents of Ulmen rebuilt their houses with stones from the castle. That's why you can still see a coat of arms on some of the stables today. It wasn't until the early twentieth century that Ulmen Castle was declared a listed building and became the property of the municipality of Ulmen. The castle is always freely accessible.

Wide forest paths lead from the Alfbachtal to the Notkreuz. Here, too, in the Rudebuhrwald forest, an information board informs us that during the war years of 1944-1945, the residents of Darscheid had to seek refuge in the forest to escape the constant air raids. The wooden Notkreuz, erected here, serves to remind future generations of the horrors of war and to call for peace. Wide forest paths lead from the Notkreuz, via the adjacent HeimatSpur valleys and the Höhenweg (Heimat Trail), up to the Thommener Höhe. Here, you'll be treated to breathtaking panoramas of the Volcanic Eifel.
