Mertert, where the Moselle meets the Sûre

Mertert is the last stop but one on the Luxembourg Moselle valley before the river takes in the Sûre and heads off towards Trier. It hasn’t got Remich’s promenade or Wormeldange’s steep vines, which is exactly why I like it for a walk without coach parties. The commune had 5,685 residents on 1 January 2026 and just two localities, Mertert itself and Wasserbillig.

A park where two rivers meet

The first thing you reach is the park. visitluxembourg places it where the Moselle and the Sûre meet and sells it on a fountain and an old-fashioned pavilion that add a bit of romance to the heritage trail. It also has an outdoor fitness course, a boules court, a tree adventure trail, a playground and a water play area, with concerts and events through the year. Think well-kept local park rather than historic garden and you won’t be disappointed.

The former castle grounds, with their pond, hold the commune’s campsite, which the national tourist board rates first class. There are no hotels, as STATEC counted none in 2025.

The Syre, the wild side

The real draw for me is the circular walk. It’s 10.69 km, around three hours and 427 metres of climbing, so allow for proper effort. It starts at the Rue du Parc car park, crosses the castle grounds and follows the Syre uphill past a waterfall into Manternacher Fiels, which the official listing calls the country’s most important ravine forest. Along the way come the ruins of an old wooden mill, a viewpoint up some steps at the Meschelslay and the Schlammbach stream before you drop back over the Widderberg.

If you’d rather keep it flat, the tourist board suggests strolls along the Moselle and the Syre through vineyards and woodland. There are plenty more walks like this across the country. To look down on Mertert, the short loop from Machtum climbs to the Haangeberg viewpoint, which takes in the river bend with Machtum, Grevenmacher and Mertert.

Once your dates are set, check which hotels are still free in Grevenmacher before prices climb.

Port, wine and summer festivals

Mertert has a river port, and the regional tourist office mentions wine and park festivals in June and July. I couldn’t find fixed dates published, so check the local listings before you plan around them. For wine tasting you’re better off a little upriver in Grevenmacher or in Wormeldange, the commune that calls itself the capital of Riesling, where the cooperative cellars and the Koeppchen chapel are a short bus ride away. Mertert is where I’d walk, not where I’d drink.

Getting there

Here the train genuinely works. Mertert is one of only two places on the Luxembourg Moselle on the CFL station list, on the Luxembourg to Trier line, and second class is free within the country. The bus stop by the park is Mertert, Parc. I’d take the train out, walk the riverbank to Wasserbillig next door and ride back from there. With children, that’s where the Wasserbillig aquarium is, small and free with the LuxembourgPass. If you fancy carrying on into Germany, the Trier day trip uses the same line.

Once your dates are set, check which hotels are still free in Grevenmacher before prices climb.

If you would rather have a local show you round, book a guided tour in Grevenmacher 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.
