Strada dell’Assietta – Italy
Alpine military road at the edge of the sky
The Strada dell’Assietta cuts a knife-edge line across the spine of the Cottian Alps, following an old military road built by the Savoy army in the 18th century. This 35-kilometer route connects Sestriere to the Colle dell’Assietta at 2,472 meters, with sections that drop off into France on one side and Italy on the other. The road passes Fort Assietta, where Piedmontese forces held off French attacks in 1747, and offers unobstructed views across the Western Alps to Mont Blanc.
Rated moderate to difficult depending on conditions, this route demands high-clearance vehicles with solid traction control due to loose rock sections and exposed switchbacks. Open July through September when snow clears, the road can turn treacherous in fog or afternoon thunderstorms. No permits required, but fuel up in Sestriere and carry extra water. Wild camping is possible at designated areas near the pass. This is pure Alpine overlanding – thin air, big views, and the kind of terrain that separates weekend warriors from serious mountain drivers.

Frequently asked questions
Can a stock Jeep Wrangler or Land Cruiser handle the Assietta without modifications?
Yes — a stock high-clearance 4WD handles it fine in dry summer conditions. The road is rough gravel with embedded rocks and some eroded sections, but nothing requires a lift or lockers. Skid plates are a smart precaution given the sharp rock debris.
When does the Strada dell'Assietta actually open and close each year?
Typically opens late June to early July depending on snowpack and closes by mid-October. July through September is the reliable window. Snow can linger on the high sections well into June and return early in autumn — don't guess, check local conditions from the Province of Turin or Sestriere tourist office before you go.
Do you need a permit or pay a fee to drive the Assietta?
No permit or fee required as of current information — it's a public road managed by the Province of Turin. Some sections fall within protected alpine zones, so stay on the main track and don't camp in restricted areas. Regulations can change seasonally, so confirm with the Province of Turin before your trip.
What's the hardest section of the route and what makes it technical?
The ridge sections near the old military fortifications are the gnarliest — narrow shelf road with no guardrails, loose gravel, and steep drop-offs on one side. The trail also has several rocky eroded pitches that will test your suspension articulation and your nerves equally. Meeting another vehicle on the narrower sections means someone is backing up, sometimes a long way.
Is there any gas or water along the 22-mile route, and how far is the nearest fuel from the trailhead?
Zero services on the trail itself — no gas, no water, no bailout options once you're on the ridge. Fill up in Sestriere before you start. Carry at least 3–4 liters of water per person; the high alpine exposure at 8,000+ feet hits harder than you expect, especially on a warm July day.
