For more than 20 years, natur&ëmwelt has been organising the "En Dag an der Natur" campaign with its partners; this year, its 26th edition, it takes place from 1 April to 31 August 2023 under the patronage of Luxembourg's Ministry of Environment, Climate and Sustainable Development. 

The objective of this campaign is to give a wide public the opportunity to approach the local landscape, animal and plant heritage in an exciting and lively way and to perceive it as a precious asset worthy of protection.

The 2023 edition consists of around 300 activities brought together by more than 100 organisers.

A paper version (in German) of the nature activities offer can be ordered from natur&ëmwelt at email: or by tel: 290404-1. In digital version, the brochure is available in German and French online at

natur&ëmwelt advises anyone wishing to participate in an activity to notify the organiser in advance.
