The Fort of Infernet, located in the Susa Valley, is one of the fortifications of the region, built between the 19th and early 20th centuries as part of the Italian defensive system against potential French threats. This fort is located at about 2,800 meters above sea level and is strategically positioned to control the surrounding valleys. The Infernet was designed primarily as a high-altitude battery, with a robust structure capable of housing cannons and a limited crew. Its dominant position offered a strategic view of the valley and important control over the connections between Italy and France. Today the site can be visited, although in not perfectly preserved conditions, and is an interesting destination for hikers and military history enthusiasts

The region around La Salle-Les-Alpes is known for its impressive military fortifications rather than traditional medieval castles. These include structures designed by Vauban, high-altitude forts, and other defensive sites that reflect the area's strategic importance in the French Alps. Many offer historical insights and panoramic views.
The Vauban Fortifications of Briançon are a UNESCO World Heritage Site. This network includes a 3-kilometer wall encircling the town, along with four main forts: Fort des Salettes, Fort des Trois Têtes, Fort Dauphin, and Fort du Randouillet. The Asfeld Bridge is also a notable element of this defensive system.
Yes, the Briançon Castle (Fort du Château) is partially accessible to visitors. While the medieval structure was replaced, the site offers strategic ramparts and barracks. Guided tours are often available, especially during the summer, providing insights into its history and unique setting as part of Briançon's UNESCO fortifications.
Absolutely. The Mont Chaberton Fort, also known as the 'Fort of the Clouds,' is one of Europe's highest forts at 3,131 meters. It's a popular and challenging hiking destination, offering incredible panoramic views of the surrounding mountains and a unique piece of World War history. Another high-altitude option is Fort Lenlon, situated at 2,508 meters, which can be reached via the Clarée valley or Col du Granon on foot or by mountain bike.
Fort de l'Infernet is a fortification complex near Briançon, built between 1876 and 1878 at an elevation of 2,380 meters. It's notable as France's last fort built entirely from cut stone masonry. While public access to the fort itself is restricted due to safety and preservation, its remnants can be observed via marked hiking trails, offering stunning mountain scenery and a glimpse into 19th-century military defense.
Yes, many of these fortifications are accessible via hiking trails. For instance, you can find routes that lead to the Briançon fortifications. The region offers a variety of hiking experiences, from easy walks to challenging climbs. You can explore various hiking routes around the area by checking out the Hiking around La Salle-Les-Alpes guide.
The historic town of Briançon, with its UNESCO-listed Vauban fortifications, offers a family-friendly experience. You can stroll through the historic Cité Vauban, explore the ramparts, and enjoy the atmosphere. While some high-altitude forts require challenging hikes, the main Briançon fortifications are more accessible for families.
Due to the mountainous terrain and the historical nature of the fortifications, many sites, especially the high-altitude forts like Mont Chaberton or Fort de l'Infernet, have limited accessibility. However, parts of the Vauban fortifications within Briançon's historic town may offer more accessible paths and viewpoints, though cobbled streets and inclines are common.
Many hiking trails in the Serre Chevalier valley are dog-friendly, allowing you to explore the natural surroundings and approach some of the fortifications. However, specific rules may apply within the fortifications themselves, especially if they are managed sites or have guided tours. Always check local regulations and keep your dog on a leash.
The summer months (June to September) are generally the best time to visit, as the weather is mild, and high-altitude trails are clear of snow. Many sites, like the Briançon Castle, offer guided tours during this period. Visiting in late spring or early autumn can also be pleasant, with fewer crowds and beautiful scenery, though some higher routes might still have snow or experience colder conditions.
Beyond exploring the fortifications, the region offers a wealth of outdoor activities. You can find numerous hiking trails, from easy walks to challenging climbs, as well as extensive road cycling and mountain biking routes. For more details on routes, check out the Hiking around La Salle-Les-Alpes, Road Cycling Routes around La Salle-Les-Alpes, and MTB Trails around La Salle-Les-Alpes guides.
