INTRO

One of three routes to the mighty Passo dello Stelvio, and the only one that begins in Switzerland. We begin this climb in Santa Maria Val Mustair, at the southeastern tip of Switzerland, and climb 8.1 miles and 3,650 feet at 8.5% average grade to the Swiss/Italian border at Umbrail Pass. From there it's a further 2 miles and 855 feet at 8.4% to Passo dello Stelvio - in all, 10.1 miles and 4,605 feet at 8.5% average grade, with the steepest quarter-mile at 13.0% and the steepest full mile at 9.9%. The Umbrail side is the quiet one - switchback after switchback through open, high-alpine terrain, with far less traffic than the famous Bormio or Prato allo Stelvio sides. That changes at the top: crest Umbrail Pass, continue 2 more miles into Italy, and Passo dello Stelvio erupts into cafes, bratwurst stands, and one of the liveliest finish-line atmospheres of any climb we've ridden. The Giro d'Italia first climbed this exact route in 2017, when avalanche risk on the standard Stelvio approach forced a reroute of Stage 16 over Umbrail Pass, which became that year's Cima Coppi, the race's highest point. Fully paved since 2015, typically open late May through late October, snow permitting - check current conditions before a shoulder-season ride.

This climb builds gradually rather than punishing you all at once. Average grade holds at 8.5% across all 10.1 miles, and it barely varies by section: the steepest quarter-mile touches 11.9%, the steepest half-mile 10.0%, and the steepest full mile 9.6%. The single toughest stretch comes right near the end - a steep kilometer beginning about 1 km from the summit, at roughly 10.3%. Both halves of the climb (Santa Maria to Umbrail Pass, then Umbrail Pass to Stelvio) hold almost identical average grades - 8.5% and 8.4% - so there's no easier or harder section to plan around, just a long, consistent grind to just under 9,000 feet.

Roadway: The road has been fully paved since 2015 and is well maintained throughout - a narrow but smooth surface with numerous switchbacks, especially in the upper half. If you continue past Umbrail Pass to Stelvio, the final 2 miles into Italy are on the same well-known, immaculately maintained Stelvio tarmac.

Traffic: Traffic on the Umbrail side is noticeably lighter than the more famous approaches to Stelvio from Bormio or Prato allo Stelvio - this is the quiet way up. That said, it's still a through road connecting Switzerland and Italy, so expect some car and motorcycle traffic, especially in July and August. Occasional event-related closures do occur - in 2026, for example, a cycling event closed the Bormio-Stelvio section for several hours on July 12 while the Umbrail side stayed open to the border as normal - so it's worth checking current road status if you're riding in peak season.

Parking: There's no dedicated cycling lot at the start. Riders typically park in Santa Maria Val Mustair near the Route 28/Via Umbrail junction, or in one of the small villages just north of town.

This is a long, steady effort at altitude - the summit sits just under 9,000 feet, so expect cooler temperatures and thinner air even in summer, and pack a layer for the descent regardless of how warm it is at the bottom. There are no services between Santa Maria and the top other than what's available right at Passo dello Stelvio itself, where cafes and food stands cluster around the summit - a good place to refuel before heading back down. Standard climbing gearing is enough for the consistent 8.5% grade; there's no need for anything lower than what you'd use on a typical long alpine climb.

We stayed five miles north of the start of the climb at Hotel al-Rom in Tschierv, Switzerland, and found the accommodations, staff, and restaurant excellent - a good base for tackling Umbrail early in the day. Santa Maria Val Mustair itself sits in one of Switzerland's most remote valleys, right on the Italian border, so it's worth combining this climb with a night or two in the area rather than a rushed day trip. The road is typically open from late May through late October depending on snowfall - our Weather tool is a good way to check conditions at both the base and summit before you go, especially in the shoulder season. And once you reach the top, don't rush back down: the summit at Passo dello Stelvio has one of the liveliest at-the-top atmospheres of any climb in the Alps, well worth lingering over a bratwurst before the descent.
