The seasonAll the passes are still open, the air is clear and cold at the tops, and the alpine descents are quiet after the August traffic. How we read the weather window · the September edition.
The Soul Score is BicycleMovement's official figure for this route, shown here exactly as published on High Meadow Traverse route page.
August is the safest month for a high alpine traverse: every pass on the route is fully open, the meadows are at their fullest, and the mornings are clear before the afternoon build-up. Thunderstorms form over the summits most afternoons, which is an argument for early starts rather than for a different month. Carry warm layers — the tops are cold even in a heatwave.
We would avoid before June, when snow still closes the high roads. See the month-by-month weather window for Switzerland
Old pass roads mean steady, well-graded climbing rather than brutal gradients, but the days are long and the altitude is real. Descents are fast and cold. Fitness matters more than technique here.
On the roadOld pass roads left quiet since the tunnels opened: steady gradients, good surface, and long alpine descents. Passes are fully open in August; carry warm layers for the tops even on the mildest days.
Gradients, surface changes and the full elevation profile are published on the official High Meadow Traverse page on BicycleMovement, which is the complete version of this journey.
Pass roads the tunnels left behind
Traffic went underground decades ago; the old road over the top is quiet and beautifully surfaced.
Grimsel and the high lakes
Granite, dammed water and thin air, with the road drawn across it in long clean lines.
Meadows in full August growth
Cowbells, wildflowers and hay being cut on slopes too steep for machinery.
Descents that last an hour
Long, sweeping, cold — the reward for every climb, and the reason for the extra layer.
6 days of riding, 340 km and 7,300 m of ascent, shaped the way we would ride it — short mornings, long afternoons, and no day that has to be finished.
Days 1–2
Valley approach
Gradual valley roads and the first pass, ridden early before the afternoon build-up.
Days 3–4
The high passes
The heart of the route: two big climbs, meadows in flower, snow banks at the top in early season.
Day 5
Old road
The pre-tunnel pass road — sealed, nearly empty, and the quietest day of the traverse.
Day 6
Long descent
Down the far side into warmer air and a valley train home.
