Nature Park Safari 2021

3 nature parks – 2 months – 1.000 species

15 July – 15 September

Help us find more than 1,000 species in the 3 Nature Parks of Luxembourg in 2 months.

You too can support the Citizen Science project of the three Luxembourg Nature Parks. Get to know and better understand your natural environment and contribute to science at the same time. As a Citizen Scientist, collect, create and share useful data and help scientists better understand when and where creatures occur.

Every observation, from the rarest insect to the most common wild weed, can contribute to biodiversity research. With the help of iNaturalist, a global online social network based on crowdsourcing observations and determinations, you share your observations with naturalists, citizen scientists as well as biologists and contribute to the collection of important data.

All you need to do is observe. iNaturalist can be accessed via its website ( or via its mobile apps (iOS/Android).

Thank you for your assistance. The status of the Challenge can be viewed at any time in the iNaturalist project “NATURE PARK SAFARI Luxembourg 2021”.

iNaturalist Challenge „Insekteräich Naturparken“

Starting signal for the iNaturalist Challenge “Insekteräich Naturparken”.

WaterWalls Festival

WaterWalls is het eerste culturele festival gebaseerd op ‘cradle-to-cradle’-principes. Het wordt vanaf 2021 als tweejaarlijks evenement georganiseerd en vindt plaats in Esch-sur-Sûre van 17 juli tot 25 september.

De hele zomer lang zullen eigentijdse kunstwerken in de omgeving van de vier stuwdammen stroomafwaarts van de Grand Barrage en een vijfde stuwdam langs de vallei van de Sûre het decor vormen voor voorstellingen, concerten, geluidsexperimenten of zelfs conferenties en debatten in een buitengewoon landschap.

Het thema van deze eerste editie, ” Natural Borders “, nodigt uit tot reflectie over de grenzen tussen oorspronkelijke en artificiële natuur, en leent zich tot tal van metaforen en vragen over stromingen, technologieën, de grenzen van natuur en menselijk ingrijpen, en de gevolgen van deze andere barrières gecreëerd door de stuwdam. Het kunstfestival is daarom een manier om mensen bewust te maken van de milieuproblematiek door middel van een artistieke, ludieke, participatieve en educatieve aanpak.

Het WaterWalls festival streeft ernaar een hedendaags totaalkunstwerk te presenteren dat het publiek bewustwil maken van de artistieke productie en de aspecten van culturele consumptie. Om op deze benaderingswijze in te spelen, werden de kunstenaars uitgenodigd te creëren of te co-creëren, rekening houdend met criteria van duurzaamheid en circulaire economie.

Zo kunt u 5 artistieke en scenografische installaties ontdekken waarvan het ontwerp en de expressie zo nauw mogelijk aansluiten bij de “3R-strategie”: reduce, reuse, recycle.

De voorstellingen en activiteiten die de hele zomer door plaatsvinden, zijn bedoeld voor alle publieksgroepen.

De geselecteerde kunstenaars en projecten zijn :

  • YO studio en Lagerkultur: “STAU”
  • Justine Blau en Stéphane Ghislain Roussel : “Ressac|re”
  • MAD TRIX : “Nénuphars” (stART-up prijs)
  • Serge Ecker en Giacomo Piovan : “Floating Pixel”
  • Marco Godinho en Fábio Godinho : “Offrir quelques mots à la rive”

Programma en kaartverkoop:


Bathing season on the Upper-Sûre lake

From Saturday 22 May, the booking system will be in place until the end of the bathing season. Online reservations can be made free of charge from 20 May via or the Éislek app. While in 2020 visitors only had to make reservations on weekends and public holidays, reservations are now mandatory on weekdays as well. Those who have already booked their tickets and then are unable to visit the booked beach area, should cancel their reservations by sending an email to Activities during which visitors do not stay on the beaches are excluded from booking. Accordingly, visitors do not need to make a reservation if they want to hike along the reservoir or go kayaking or fishing on the lake, for example. The current hygienic measures also apply when visiting the Upper-Sûre lake. Thus, a distance of at least 2 metres from other visitors must be maintained and when more than 4 people are gathered, the wearing of a mask is obligatory. The wearing of a mask and the physical distance of at least 2 metres do not apply to people who belong to the same household or who live together. Children under 6 years of age and persons with a disability or pathology who are in possession of an appropriate medical certificate are excluded from the mask obligation and the distance rule as well.

New season for the Stauséi-Shuttle

Bus line 690 – Stauséi-Shuttle starts its round trip around the lake again on 09.05.

In the morning to the Cloth Factory in Esch-sur-Sûre, then hiking in the direction of Kaundorf and finally conclude your trip at Houfels? And where to park the car? At home, because with the Stauséi-Shuttle you can easily explore many attractive destinations around the reservoir without having to worry about how to get there or back to your car. The shuttle runs hourly in both directions around the reservoir. At the start of the shuttle in May until June, there will unfortunately be an increase in journey time of approx. 15 minutes in both directions between the stops ARSDORF, Misärsbreck (Parking) and BOULAIDE, Post Office, due to the roadworks at Pont-Misère.

Go to and find the itinerary that suits you best.


Natura 2000 sites play a significant role in the protection of water resources and wetlands. In the framework of the World Water Day on 22 March, the two nature parks Öewersauer and Our, together with the nature conservation centre Burfelt of the nature agency, therefore invite you to explore the Natura 2000 sites of the Luxembourg Ardennes – on 12 selected hiking trails – by yourself.

Living joints around your house

Increase the biodiversity around your house by greening the joints between paving stones, pavement slabs or clinker bricks! The 3 Luxembourg Nature Parks provide a sample pack of 5 g “joint mixture” free of charge to interested participants. It is a seed mixture with small and drought-tolerant species that can easily be swept into the joints.

If you are interested, please send us an e-mail with your name and address.

Foundation of the grain cooperative “Käre vum Séi”

The Öewersauer Nature Park, the SEBES and the LAKU are pleased to announce that on 9 February 2021 the cooperative “Käre vum Séi” was officially founded. A total of 19 farms have joined forces under the name “Käre vum Séi” to grow wheat, spelt and rye in the region of the Öewersauer Nature Park under increased water protection standards. The cooperative has set itself the goal of protecting soil and water and marketing the grain independently. In this way, the farmers actively participate in water protection in the reservoir region and also secure fair payment. This is guaranteed by the bakery Jos & Jean-Marie – Gebäck vum Séi. Jean-Marie Neuberg, one of the managers of the bakery, has worked towards fair payment for the farmers and thus shows great respect for the agricultural work in the region.

“Loscht op Natur – Swallows” and “Swallows in the nature park”

The biological Station of the Naturpark has edited a new information sheet on the theme of “Swallows”. It treats their biology and the protection possibilities.

To support the house martins in the nature park of the Upper Sûre, we offer to install articial nests and droppings boards on the houses of interested inhabitants of our communes. The nests and the boards will be cleaned during the following years, one time per year, by the nature park.

As the artificial nests should be installed this winter/ early spring, the interested participants should contact us until the 15th of February 2021 by email (ecology@naturpark-sure).

Éislek on its way to become the FIRST “Leading Hiking Region”

The marking has begun!
The Éislek offers ideal conditions for becoming one of the top hiking regions in Europe, which is exactly what the Regional Tourism Board Éislek is working towards within the framework of the LEADER project “Qualitéitswanderregioun Éislek”. After intensive coordination with the partners of the region, the planning work has been completed so far and the infrastructural work on the hiking trails has begun. The intention is to strengthen the region even more and to increase the hiking experience for locals as well as for guests.
