This route covers 27km return.It involves around 1,050m of cumulative elevation gain.
The route reaches roughly 1,948m at its highest point. While the altitude is moderate, weather exposure and wind can make conditions feel more demanding than the elevation suggests.
Technically, the Urnerboden to Altdorf (Klausenpass Route) standard trail is a scramble. The primary difficulty is the sustained physical effort required or technical terrain features.
Overview
Technical Summary
Technically Stage 8 of the Swiss Via Alpina, this traverse crosses the border between the Cantons of Glarus and Uri. Starting at Urnerboden—Switzerland's largest alpine pasture—the trail climbs toward the Klausenpass before a massive, spectacular descent into the Schächental valley.
The Mist and the Limestone Spires. The 'X-Factor' here is the atmospheric quality of the Schächental. In autumn (October), it is common for the valley floor to be filled with a 'sea of fog' (Nebelmeer), while the trail stays in glorious sunshine. Looking across the white mist to the jagged, needle-like peaks of the Schärhorn creates a scene of ethereal beauty that feels isolated from the modern world.
Hazard Assessment
The final 1,900m descent from the high trail into Altdorf is incredibly taxing on the quadriceps and knees.
If the fog rises to the trail level, visibility can drop, making it hard to follow the white-red-white markers through the pastures.
The Expert Take
Success on this route requires balancing physical stamina with environmental awareness.Local conditions shift rapidly; always verify forecasts with regional authorities before moving to higher ground.

Route Questions
Is it too long for one day?
At 27km, it is a very long day. Many hikers stay overnight at the Klausenpass pass-hotel to split the route.
Do permit rules stay constant year-round?
Not always. Permit and guide requirements can change by season and region. Verify the latest rules with the official park office or local authority before departure.
What is the safest start-time strategy?
Start early and plan to clear exposed sections before midday. This reduces heat, storm, and visibility risk on most mountain routes.
How much water capacity is usually needed?
For exposed hiking days, carrying 2-3 liters is common. Increase capacity when refill reliability is low or temperatures are high.
Is mobile signal reliable on route?
Coverage is often patchy outside towns and major valleys. Treat phones as secondary tools and carry offline navigation resources.
