Roads worth driving.
Kurvli reads the geometry of every mountain road in the Alps and finds the ones that reward a good driver — then rates them like pistes, counts their hairpins, and gets you to the first corner.

The rating
You already know how to read a mountain.
Curvature scores mean nothing to a newcomer, so Kurvli borrows the language every mountain town speaks: ski-run difficulty. Every road gets a badge.
Flowing
score 300–599
Relaxed and scenic. Sweeping bends, no drama — the warm-up valley road.
Twisty
score 600–999
Properly engaging. Earns your attention and holds it for the whole climb.
Relentless
score 1000+
Corner after corner after corner. A driver’s road, full stop.
Legendary
curated
The hand-picked icons — Susten, Klausen, Bernina, and their kind.
The portraits
Every road draws its own picture.
No stock photography here. Each road’s portrait is its actual geometry, rendered as an alpenglow ribbon — the shape of the road is the artwork. These three are real, from real data:
Strada del Pass
The Tremola, San Gottardo · Ticino
- Hairpins
- 101
- Length
- 51.1 km
- Summit
- 2,068 m
- Ascent
- 1,831 m
Furkastrasse
Furkapass · Uri / Valais
- Hairpins
- 42
- Length
- 37.8 km
- Summit
- 2,427 m
- Ascent
- 1,110 m
The stat that matters is the hairpin count — corners in the tightest radius bucket, counted along every road and worn like a badge of honour. Say “101 hairpins” to anyone who knows, and they’ll know you mean the Tremola.
The drive
From “free afternoon” to the first corner.
The nicest route
Not the fastest way — the best one. Ask for Zürich to Lugano and it will send you over the Gotthard’s cobbled Tremola, if you let it.
Loops that fit your day
Tell it you have three hours from Andermatt. It hands back Susten–Furka–Grimsel — with honest driving times, closed passes excluded.
Drive Mode
A follow-me map, a countdown to the next hairpin, and a haptic tick as you clip each one. Eyes on the road, always.
Feel the climb
Scrub along any road’s elevation profile and feel every hairpin click past under your thumb.
Built for no signal
Offline maps and saved roads, because the best corners have the worst coverage. The mountains don’t do 5G.
Share the road
Every road renders a collectible card — ribbon, badge, hairpin count. Send the card; the road does the bragging. GPX export for the rest of your kit.

Measured, not guessed.
