This route is rated as moderate. While some sections might be on dirt roads or forest trails, Alpine terrain can include rocky or uneven paths. Beginners with good basic fitness should be able to manage it, but be prepared for varied conditions and some elevation.
The starting point for exploring the Roman ruins is typically near the Little St. Bernard Pass. Parking facilities are generally available in this area. Specific parking for CAI trail 9 would be found close to the Roman remains at the pass.
The route is rich in history and scenic beauty. You'll encounter ancient Roman ruins, including vestiges of a mansio and a fanum, and sections of the ancient Roman Road to Gaul. Further along, you can enjoy panoramic views from Les Suches 2,200, offering vistas of Mont Blanc and other Alpine peaks.
The terrain is characteristic of an Alpine environment. Expect a mix of varied paths, including segments on dirt roads, forest trails, and potentially rocky sections. You'll traverse meadows, pastures, and woodlands, often with streams and possibly marshy areas near Lac de Touriasse.
Generally, trails in the Aosta Valley are dog-friendly, but specific leash rules may apply, especially in protected areas or near livestock. Always keep your dog under control and clean up after them. Check local signage for any restrictions.
The best time to hike this Alpine route is typically from late spring to early autumn (June to September). During these months, the weather is generally more stable, and the trails are clear of snow. Early season might still have snow patches at higher elevations.
As of current information, there are no specific permits or entrance fees required for hiking this particular trail or accessing the general Espace San Bernardo area. However, it's always advisable to check for any updates from local authorities before your trip, especially if you plan to visit specific attractions.
Yes, the route also passes through sections of the sentiero T. This means you might encounter other hikers or have options to extend your journey onto connecting trails.
Given the moderate difficulty and Alpine environment, pack appropriate hiking boots, layers of clothing (even in summer, weather can change quickly), rain gear, sun protection, sufficient water, snacks, and a map or GPS device. Trekking poles can also be helpful for varied terrain.
Winter hiking in the Alpine region around Lac de Touriasse can be challenging and requires specialized equipment like snowshoes or skis, avalanche safety gear, and significant experience. Many trails may be impassable or dangerous due to snow and ice. It's best to consult local guides or conditions reports before attempting this route in winter.
To fully appreciate the historical significance without rushing, consider starting your hike early in the morning. This allows for ample time to explore the Roman ruins at the Little St. Bernard Pass before continuing towards Lac de Touriasse, often avoiding the busiest times and enjoying the serene Alpine landscape.
