Conference Debate - The impact of outdoor activities

Come and participate in the conference debate that we are organizing with the Groupe Tétras Jura which will focus on the impact of outdoor activities on wildlife and the Grand Tétra.
This conference will be held at L'Omnibus in Les Rousses at 6:30 pm.
As you know, since 2009 we have been committed to a responsible approach in order to become a major player in our beautiful region.
Each year, we build environmental files that determine whether or not the Transju events will take place. You can consult these files and our actions right HERE.
