Stella Alpina Military Road Circuit
WWI fortifications meet extreme alpine 4x4 challenges
The Stella Alpina winds through high-altitude military positions built during WWI when this was the Austrian front line. You’ll navigate narrow ledge roads carved into limestone cliffs, pass through the ruins of Fort Tre Sassi, and tackle the infamous Passo Valparola switchbacks where Austrian soldiers once hauled artillery. The route connects multiple fortified positions including the underground galleries of Lagazuoi, demanding precise wheel placement on exposed sections above 2,000-meter drops.
This is expert-level alpine driving requiring a capable 4WD with low range, skid plates, and recovery gear. Roads turn treacherous with weather changes, and several sections demand spotting around blind hairpins. Best tackled June through September when snow clears the high passes. Fuel up in Cortina d’Ampezzo before starting—no services exist on the circuit. What you get is unmatched Dolomites scenery, WWI history you can touch, and technical driving that’ll test your limits on some of Europe’s most dramatic mountain roads.

Frequently asked questions
Can a lightly lifted Jeep Wrangler or Defender handle this trail, or does it need serious mods?
A stock Jeep or Defender won't cut it here. You need a modified 4WD with low range, good articulation, and ideally a skid plate setup — the rocky sections at altitude are unforgiving and there's no easy bailout if you damage something underneath.
When does the Stella Alpina circuit actually open, and is snow a real concern in early June?
The trail is best run June through September, but early June means you can still hit snow and ice at elevations pushing 7,800 feet. Wait until late June if you're not equipped with snow chains or all-terrain tires with winter ratings.
Do you need a permit to run this circuit inside the Parco Naturale delle Dolomiti d'Ampezzo?
Yes — the Parco Naturale delle Dolomiti d'Ampezzo manages this area and vehicle access permits are required. Contact the park authority directly before your trip, as enforcement has increased and fines are real.
What's the hardest section of this trail and what specifically makes it dangerous?
The exposed ridge traverses on the original WWI military road are the crux — narrow shelves cut into cliff faces with no guardrails, significant drop-offs, and loose rock that shifts under tire. One wrong line and recovery becomes a very serious situation.
Is there anywhere to get fuel or resupply near the trailhead, or do you need to leave Cortina d'Ampezzo topped off?
Leave Cortina d'Ampezzo with a full tank — there are no fuel stops on or near the circuit. At 28 miles with sustained low-range crawling and altitude, fuel consumption runs higher than expected, so plan accordingly.
