Your daytrip to the Marcharuz Pass

Discovering the Wood Ant trail

The Parc Jura vaudois is one of Switzerland’s regional nature parks, which has been recognized as a park of national importance since 2013. The Parc extends over 531 km2 (covering 20% of the canton of Vaud) from the summit of La Dôle to the village of Romainmôtier. The Marchairuz Pass marvellously unites four regions and its people

Start you adventure at the Marchairuz Pass and discover the trail of the wood ant “Gaia”. “Formica rufa”, known as the red wood ant for its colour, plays an essential role in our forests. So much so that in 1966, it became the first insect in Switzerland to be given protected status. There are ten points along the red wood ant trail presenting these likeable insects and their specific features. An educational and fun attraction to discover with family or friends.

Note: the trail is easy and suitable for children. However, it is not accessible to pushchairs or wheelchairs. The trial is not supervised and not cleared in snowy conditions. Free access.

In autumn 2020, the Jura Vaudois Park opened its first public information center, the “Espace découvertes”, located in the east wing of the Hôtel-Restaurant du Marchairuz. It is open at the same times as the restaurant, and admission is free. It houses a permanent exhibition detailing the tasks the Confederation has entrusted to Swiss regional nature parks. 
It will present the park’s projects linked to the landscape, biodiversity, sustainable tourism, the promotion of local products and the local economy, and increased awareness of sustainable development.

You can also enjoy a walk along the Simeon Fir Tree Trail, which has been renewed and renovated. Ten information points detail the richness of the nature surrounding you and tell you all about the history of the park’s forestry and eco-system.
