Passo dello Spluga South — Madesimo to Chiavenna via the Italian Alpine Wall Descent
Roman road. Cliff edge. No margin for error.
The Spluga Pass has been a crossing point since Roman times, and the southern descent from Madesimo to Chiavenna makes it immediately obvious why armies and merchants sweated through it for centuries. From the summit at 2,115 metres, the road plummets toward the Liro Valley in a series of tight, stacked hairpins carved directly into the cliff face — some partially tunnelled through rock overhangs. The guardrails are thin, the drop is real, and the pavement is narrow enough that two vehicles passing requires genuine cooperation. The Val Cardinello section, roughly halfway down, is the most exposed stretch: open cliff, no margin, full commitment.
This is a paved road, not a 4×4 trail, but it earns its place in any overland itinerary on sheer drama and historical weight alone. Any vehicle with decent brakes can run it, but overloaded trailers and large overlanding rigs need to take the descent slow and methodical — brake fade is a real concern. Open June through October weather permitting; the pass closes under snow. No permits. Fuel in Madesimo before you drop. Chiavenna at the bottom has good food and cold beer, which you’ll want after white-knuckling those switchbacks.

Frequently asked questions
Can I drive this in my full-size truck or large camper van?
Technically yes, but the 48 hairpins are tight and some switchbacks will demand multi-point turns in a long-wheelbase rig. Stock trucks and SUVs handle it fine. Large camper vans or trailers — know your turning radius before you commit, because there's nowhere to bail once you're on the wall.
When does the pass close for winter and when does it reopen?
Passo dello Spluga typically closes with first heavy snowfall, usually November, and reopens around May or June depending on the year. June through October is the reliable window. Check current status with ANAS or Provincia di Sondrio before you go — late spring closures due to snowpack aren't rare.
Do I need any permits or pay any fees to drive this route?
No permits and no tolls for the descent itself. It's a public road managed by ANAS. If you're crossing from Switzerland, standard Schengen border crossing rules apply — no vignette needed on the Italian side.
What's the hardest part of the descent and what makes it technically demanding?
The upper section immediately below the pass is the most exposed — cliff edge, no guardrail in places, and switchbacks that tighten faster than they look on a map. The real challenge is brake management over 1,800 metres of continuous descent; overheated brakes on this road are a serious problem, not an inconvenience.
Is there anywhere to stop for fuel or water between Madesimo and Chiavenna?
There are no fuel stations on the descent itself — fuel up in Madesimo before you start or in Chiavenna when you arrive. The 30km route is well within range for any vehicle, but don't count on finding services mid-descent. Water and basic supplies are available in Chiavenna at the bottom.
