Ornon can be explored from several perspectives: almost the entire municipality is included in the Natura 2000 network; the Plateau du Taillefer is a mosaic of small lakes and Arctic grasslands. At Col d’Ornon, there are marked snowshoeing loops and geological sites. When planning your trip, you can therefore focus on the landscape, winter activities or geology. Practical conditions vary: the snowshoeing loops are seasonal, and access to the hike to Refuge du Taillefer depends on the weather and snow conditions.

Landscape between plateau and forest

The Plateau du Taillefer is a mosaic of small lakes and Arctic grasslands. Together with the extensive inclusion of the municipality in the Natura 2000 network, this offers a view of two different scales: the landscape of a named plateau and the municipality’s connection with nature as a whole. The white alder forest is also located at Col d’Ornon. It covers 200 hectares; the tourism description calls it the largest in France and possibly in Europe. Alongside the lakes and grasslands, these are further specific natural features to consider when planning your trip.

Snowshoeing loops at Col d’Ornon

There are seven marked snowshoeing loops at Col d’Ornon. They range in length from 800 metres to 5.4 kilometres. This range gives you a concrete way to compare distances when considering a loop for your winter plans. The loops are seasonal and depend on conditions. Before setting out, check whether the current conditions suit your plans.

Geology and the formation of the Alps

The Faille du Col d’Ornon is a major geological fault. Its discovery and interpretation have contributed to our understanding of the formation of the Alps. The geological sites at Col d’Ornon are regularly visited by geology study groups, from upper secondary school classes to Grandes Écoles and universities. If you would like to include geological context in your trip, the fault offers a specific point of interest: a named geological feature with significance for the history of the Alps.

Mountain farms and the history of slate

The hamlets of Ornon include numerous traditional mountain farms, most of which have now been renovated. They form part of the built heritage and offer a different focus from the nature and geology themes. The history of slate also extends beyond Ornon: slate tiles from Ornon were transported by rail throughout France and as far as Australia. For travellers who would like to explore the local heritage alongside the landscape, there are two distinct points of interest: the traditional farms in the hamlets and the wide distribution of the slate tiles.

Hike to Refuge du Taillefer
