Terres d’Altitude is a mountain guiding and outdoor travel agency based in Le Châtelard, in the Bauges Natural Park in the French Alps. Working in mountain tourism since 1995, the team creates guided and independent adventures across the Northern Alps and other destinations, with the Bauges as its home base. Its comfortable accommodation and agency provide a starting point for exploring the surrounding mountains.

The agency offers custom-made and scheduled trips throughout the year, including guided and self-guided hiking, snowshoeing, ski touring, glacier trekking, canyoning and via ferrata. It also arranges family outings, equipment rental and trips for young people, alongside outdoor education activities. Itineraries range from short weekends to multi-day treks in places such as the Bauges, Vanoise, Beaufortain, Mont Blanc, Chartreuse, Vercors, Queyras, Italy and Corsica. Options include reduced-luggage trips and experiences suited to different ability levels. Terres d’Altitude positions its work around mountain culture and ecotourism, helping guests plan a trip tailored to their interests, whether they seek a gentle escape or a more demanding alpine adventure.
