Walking Holidays & Outdoor Adventures in Briançon UNESCO World Heritage Site
A fortified mountain town shaped by altitude, defence, and centuries of movement
Briançon is one of Europe’s highest historic towns and a UNESCO World Heritage Site recognised for its exceptional alpine fortifications. Located in the Hautes-Alpes of southeastern France, at the meeting point of several major valleys, Briançon has long been a place of strategic importance — guarding mountain passes, trade routes, and borderlands high in the Alps.
For travellers exploring the French Alps on foot, Briançon is a key junction for walking holidays and long-distance routes, including the GR5. Stone ramparts, citadels, and defensive walls sit directly above valley floors and trailheads, creating a rare setting where cultural heritage and mountain walking are inseparable. The surrounding landscape also lends itself naturally to cycling holidays and wider outdoor adventures, with high passes, quiet alpine roads, and access to some of France’s most dramatic mountain terrain. A wide range of independent places to stay within and around the old town make Briançon an ideal base or staging point for self-guided journeys.
About Briançon UNESCO World Heritage Site
Briançon was inscribed as part of the “Fortifications of Vauban” UNESCO World Heritage Site in 2008. The listing recognises a group of outstanding military works designed or influenced by the French military engineer Sébastien Le Prestre de Vauban, whose innovations reshaped defensive architecture across Europe.
At Briançon, Vauban adapted fortification design to extreme alpine conditions. The town’s walls, bastions, and surrounding forts were built to control access through key mountain passes linking France and Italy, including routes toward the Col de Montgenèvre. Together, these structures form one of the most complete examples of high-altitude military planning anywhere in Europe.
Unlike isolated monuments, Briançon remains a living town. Its fortifications sit within an active mountain environment shaped by walking routes, seasonal movement, and centuries of human presence in the Alps.

Outdoor Adventures
Briançon sits at the heart of one of the Alps’ most varied outdoor regions. Walkers can move directly from the old town into high valleys, upland paths, and long-distance routes crossing into neighbouring regions. The surrounding mountains support classic alpine walking, multi-day hut-to-hut journeys, and extended self-guided walking holidays.
Cycling is equally prominent, with legendary Alpine cols and quieter mountain roads radiating outward from the town. In summer, the wider area supports climbing, trail running, and high-altitude exploration, while winter brings skiing and snow-based activities — all framed by the town’s historic fortifications.
