The Mullerthal Trail is a 112 km three-loop walking trail in eastern Luxembourg. The three loops allow hikers to start and stop in towns or at different times. However, if you only have one day, consider the E1 loop from Echternach. On paper, it looks like a forest stroll; you aren’t expecting towering alpine peaks or sweeping ridgelines. But once you’re on it, the landscape is anything but, as it is filled with the region’s most iconic features.
E1 Hike Stats
Distance: 13.5 km (8.4 miles)
Total elevation gain: 375 meters (1230 feet)
Terrain: mostly unpaved, packed dirt or gravel paths
Type: loop
Estimated time: about 4 hours
How to get there
From Luxembourg City, take the bus (or drive) to Echternach. On the bus, it takes about an hour, with one change, depending on where you start. We started at the Luxembourg Central Train Station, so we needed to tram up to Kirchberg Plateau to catch bus 201. But there are many options – so look it up on your day of travel.
Once in town, start at the Basilica. We used the trail guide to direct us out of the city. Otherwise, the trail is perfectly signposted. Here is the All Trails Route for E1.
Start
The hike begins gently, leaving the historic streets of Echternach behind before quickly climbing into the forest. Within a short time, the town disappears, replaced by dense woodland and the first hints of what makes this trail so unique: sandstone formations rising out of the earth, moss-covered and irregular, as though shaped more by imagination than geology.
Highlights
Wollefsschlucht
One of the first standout sections is the Wollefsschlucht, a narrow rock gorge that feels more like a passageway than a trail. The path threads between tall, close-set rock walls, sometimes narrowing to the point where you instinctively turn sideways to pass through. Light filters down in thin strips, and the air cools noticeably, giving the entire stretch a quiet, almost cave-like atmosphere. Take a detour up the rock “Paulsplatte” – a rock column connected via a bridge: a little adrenaline and a nice view.
Named Sections
Not long after, the trail shifts back to the scenic forest stroll, with the sandstone rocks continuing on your left. You will soon come across “the labyrinth.” Here, the rock formations become more complex and disorienting, stacked and split into corridors, dead-ends, and winding paths. It feels playful and slightly disorienting, like navigating a natural maze. There’s a constant sense of curiosity—what’s around the next corner, where does this narrow opening lead—and it’s easy to slow your pace without even realizing it.
The next feature is the passage at Chipkapass. Similar to the labyrinth where the rocks form a pass, but this time you are walking along a metal walkway over the stream.
Historical Landmarks
At about the halfway mark, the trail opens slightly into the area around Huel Lee. A place where the natural and human histories of the region overlap. The rock faces here bear the marks of centuries-old quarrying, where circular sections were carved out to create millstones. Due to this, the cave space has an interesting symmetry, almost artistic.
One of the quieter but equally striking features is the amphitheatre. A natural rock overhang that has been adapted into a stage overlooking a semi-circular bowl, with layered stone rising around you like seating. We paused here for lunch, enjoying the scenery and wondering what it would be like to attend a show in the forest. This marked the end of our section on Mullerthal.
Looping Back
What makes this loop so compelling is the constant transition. You move from tight rock corridors to open forest, from shaded gorges to elevated viewpoints, from geological formations to traces of human history—all within a relatively short distance. It’s not a hike defined by a single destination, but by sights along the way.
The return heads up away from the rock formations, a little creek toward a thinner forest and more farmland. We found this part less varied with fewer of the dramatic features. But it was great for a relaxing end of the walk. One we did take a little detour down to was Wëlkeschkummer, a cozy little cave. The path is more gravel now, less forest dirt.
By the time the trail begins to descend back toward Echternach, you almost feel like re-emerging from another world. Back to civilization.
Echternacht town
Make sure to spend an hour or two in town as well. This is the oldest city in Luxembourg, founded in 698. Visit the Basilica, the Abbey, and the Orangery to experience the history here. The marketplace invites you to stroll and linger with its shops, numerous restaurants and cafés. We stopped at a little wine bar, Mistral, to sample some Luxembourg specials, most notably Cremant. Other attractions include the museums, the Roman villa, and the Echternach lake.
Final Thoughts
For a day hike, it’s remarkably dense. Every section offers something different, and the trail never really lets you settle into autopilot. It’s the perfect way to have a taste of Mullerthal and see the natural beauty of Luxembourg. Definitely a highlight of our trip.
