Eiger Trail
Today: read again while you read
These figures change during the day. Bivio reads them again when someone asks, and each one keeps the time it was read.
Reading today’s conditions…
°C
The local forecast from MeteoSwiss.
cm
The MeteoSwiss and SLF stations within 20 km. Bivio shows the measurement; it never works out a snow line.
Measured in the morning, read again every 3 hours- closures
- firing notices
- pastures with dogs
Published within 3 km of the trail
Read on geo.admin.ch, the Swiss federal map: closures from FEDRO and the cantons, firing notices from the Swiss Armed Forces, pastures guarded by dogs (FOEN).
The official public transport timetable, via opentransportdata.swiss. It shows a scheduled departure.
The route: the official figures
Time, ascent, descent and levels come from Hiking in Switzerland, the SwitzerlandMobility network published with the Federal Roads Office (FEDRO) and the cantons.

Walking time
The official SwitzerlandMobility time, without breaks.
Bivio shows the official figure. It also works it out again on the swisstopo terrain model: both, side by side.

Levels
The SwitzerlandMobility levels: technique (the colour of the waymarks) and fitness. What the levels mean
The terrain: measured by swisstopo
Distance and altitude are worked out on swissALTI3D, the swisstopo terrain model, which describes the ground without trees or buildings.
Terrain surveyed in 20256.0km
Distance
Measured by Bivio along the route, on the terrain.
2,339m
Highest point
The terrain altitude at the highest point of the route.
This hike climbs above 2,000 m: up there, the swisstopo terrain model is less precise, and so are the slope and ascent worked out from it.
One altitude point every 5 m
Within an 800 m corridor around the trail, with SWISSIMAGE aerial imagery at 1 m per pixel. Further out, one point every 20 m.
Around the trail: the open map and the photos
Fountains, toilets, restaurants and huts within 250 m of the route come from OpenStreetMap, the open map kept up by its contributors. The photos come from Wikimedia Commons, under a free licence.

The texts: written, then checked
Bivio writes its own stories: we don’t copy the SwitzerlandMobility descriptions.
We read the sources
Operators, municipalities, tourist offices, swisstopo, FOEN, archives. Wikipedia helps to find our way, never as the only source.
An AI helps to write
The story is drafted with the help of an AI, from those sources.
A second pass checks
An independent review takes every statement, compares it with its source and corrects what doesn’t hold up.
Hikers’ reviews are read before they go up.
On the trail, the mountain has the last word
Bivio writes what is published, with the time. Here is what you check along the way.
Signs come first
Bivio shows published closures, for example “no closure published” at a given time. The sign by the trail comes first.
The safety guideSnow on one particular stretch
You see it on the spot. Bivio shows the measurement from nearby stations, with their altitude.
Season and snowRockfall
No source publishes it in real time: you read it in the terrain.
Lifts
The timetable shows a scheduled departure. The operator confirms that it is running.
Hiking by public transportThe weather
It’s a forecast, with its margins: read it again on the morning you set off.
Your location
It stays on your phone: everything is worked out on the route, with no third-party service.
Questions people ask
Where does the walking time come from?
From SwitzerlandMobility, when the route has an official time. Otherwise Bivio shows an estimated time, labelled as such.
Does Bivio tell you whether a trail is open?
No. It shows closures published by FEDRO and the cantons, with the time they were read. On site, the signposts come first.
Are the texts written by AI?
The stories are written with the help of AI, from sources we have read, then a second pass checks every statement against its source.
Is the weather up to date?
Bivio reads MeteoSwiss's local forecast every hour and shows the time it read it.
Where can I see all the sources?
On the Sources and credits page: every source, its licence, and the credits hike by hike.
