Passo dello Spluga — Chiavenna to Splügen via the Italian-Swiss Alpine High Road
Napoleon moved an army here. Your rig can handle it.
The Passo dello Spluga — Splügenpass in German — has been connecting Lombardy to the Swiss canton of Graubünden since the Roman era, and Napoleon moved an army over it in 1800. The Italian side out of Chiavenna is the jaw-tightener: a series of tight stone-walled switchbacks blasted out of vertical rock face above the Cardinello ravine, barely wide enough for one vehicle with nowhere soft to go wrong. The road climbs from about 330 metres in Chiavenna to the pass at 2,113 metres in roughly 30km. The Swiss descent to Splügen is comparatively civilised — wider, smoother, still spectacular. The border crossing at the top is unstaffed. In season, you’ll share the road with coaches and cyclists, which keeps the pucker factor real.
Technically this is a paved mountain road, not a 4×4 trail — but the Italian approach demands a confident driver, good brakes, and nerves. Any stock vehicle with decent clearance can run it. The hard part is judgment, not hardware. Open roughly June through October depending on snowfall; the Swiss road authority and Italian weather services post closure notices online. Fuel in Chiavenna before you climb — there’s nothing at the pass. The views from the summit across the Splügen valley are worth every white knuckle on the way up.

Frequently asked questions
Can a full-size truck or long-wheelbase rig run this pass safely?
Long-wheelbase rigs can make it, but the switchbacks above Chiavenna are genuinely tight — some require multi-point turns. A shorter vehicle is far more comfortable here. If you're running a crew cab long bed, practice your reversals before the exposed sections.
When does the Spluga Pass typically open and close each year?
The pass generally opens in early to mid-June and closes with the first serious snowfall, usually October or November. Snow can hit any month at elevation — check current conditions with Kanton Graubünden or the Italian road authority before you leave Chiavenna.
Do I need a permit or pay a toll to drive the Spluga Pass?
No permit or toll is required on the pass road itself. Switzerland requires a Vignette for motorway travel, but the Splügenpass road is not a motorway — just carry your passport since you're crossing an international border.
What's the hardest section and what makes it genuinely dangerous?
The Italian side above Campodolcino is the crux — narrow stone-walled galleries, blind corners, and sheer unguarded drops with oncoming traffic. The road is paved but barely two cars wide in places, and there's nowhere to go if you misjudge. Good brakes and slow speed are not optional.
Is there anywhere to camp along the route, and how far is the nearest fuel from the pass?
There's no formal dispersed camping on the pass itself — it's a managed Alpine corridor crossing two national jurisdictions. Fuel up in Chiavenna on the Italian side before you climb; Splügen village has limited services on the Swiss side but no dedicated fuel station on the pass road. Plan for a full tank before departure.
