The Heringer Millen, the mill where the Mullerthal walks begin

The Mullerthal is named after its mills, and the Heringer Millen is the quickest way to understand why. It’s a 17th-century mill in the hamlet of Müllerthal, restored from top to bottom with its big wheel still turning, and turned into the area’s visitor centre. For anyone here to walk the rocks, it’s the natural starting point.

A mill in the valley of the millers

Mëllerdall translates as valley of the millers, a name owed to the mills that once lined its rivers and streams. The Mullerthal Trail website says the hamlet of Müllerthal was once home to one of the most important of them, open to visitors since 2009. That year it reopened as a visitor centre, run by the tourism association of the commune of Waldbillig.

Inside there’s a mill museum, the big wheel that still turns and an old wood-fired stone oven where bread is baked. visitluxembourg calls it a superbly restored mill, and it’s a rare chance around here to see working the very technology the region is named after.

Information, shop and restaurant

As well as a museum, the Heringer Millen is a tourist office. It hands out information on the surrounding walks and the region’s sights, and it has a shop area for walkers. The Trail website also mentions a Best of Wandern test centre. The mill’s restaurant, according to the official listing, is step-free with tables suited to wheelchairs and high chairs for children.

Accessibility has been thought through. visitluxembourg lists reserved parking spaces, ramp access to the office, adapted toilets with fold-down grab rails and a baby-changing table, stabilised gravel outside by the playground and a carousel that anyone can use.

When is it open?

Hours change with the season, so it’s worth checking. In 2026, always from 9:30 to 16:30, it opens every day from 25 May to 13 September; Wednesday to Sunday from 30 March to 24 May and from 14 September to 31 October; and Tuesday to Saturday from 6 January to 29 March and from 1 November to 20 December. The 2027 timetable wasn’t yet online when I checked on 29 September 2026. The published calendar also shows no opening dates between 21 December and 5 January, so if you’re coming over Christmas or New Year I’d phone ahead on +352 87 89 88.

For children there are guided visits with workshops on bread, the mill and local traditions, booked separately.

The mill on the trails

The Heringer Millen is the hub of the network. Route 3 of the Mullerthal Trail sets off from the hamlet of Müllerthal, and Route 2 passes through on its way from Berdorf to Consdorf. In the six stages the operator proposes, the mill ends the stage in from Berdorf, starts the one out to Larochette, and ends the one back from Beaufort through the Black Ernz valley.

On foot, the Schiessentümpel waterfall is about a kilometre away along local circuits W6 and W7. I’d do that walk even if I had no plans to go any further all day.

Where to head next

Two of my favourite Trail stretches start at the mill. Towards Berdorf, Route 2 crosses the Schnellert woods, which the trail website says are set to become a nature forest reserve, and runs past the rock walls of Ruetsbechschlëff and the Binzeltschlëff, Priedegtstull and Werschrummschlëff formations. Towards Consdorf, beyond the Schiessentümpel, the path climbs among rocks with names like Eilebuerg, Goldfralee and Goldkaul, reaches the Consdorf mills, where you can eat and drink, and runs through the Kuelscheier, a cleft so dark the website tells you to bring a torch. With the Heringer Millen as a base, you’ve got several days of walks without repeating yourself.

Getting there

The mill is at 1 rue des Moulins in Müllerthal, with parking about 100 m away. Arriving by bus, which costs nothing in Luxembourg, you’ll find the Müllerthal, Cascades and Müllerthal, Möllerdall stops about 100 m from the door. If you’re staying in Berdorf, the 6.4 km Trail stage brings you here on foot through the Schnellert woods. From the UK, the simplest route is a flight to Findel or the train to Luxembourg City, then the free bus out towards the Mullerthal.

If you would rather have a local show you round, book a guided tour in Heringer Millen and choose by the reviews.

A car frees you from timetables: search car hire in Luxembourg on DiscoverCars and compare companies.

So you do not pay over the odds, look at trains, coaches and flights to Luxembourg on Omio and pick the one that suits you.
