Find the twistiest roads near you and stitch them into a loop back to where you started.
Early access — routes are auto-generated and may be imperfect. Check the road ahead and drive to conditions.
Your start point and the route's waypoints are sent to Google so it can draw the directions.
Google Ireland Ltd. receives those coordinates. They may be transferred outside the EU (e.g. to the USA), where data-protection safeguards may be weaker and authorities may be able to access the data.
See the privacy notice for details. GPX export keeps everything on your device.
Controls
How far from the start to look for curvy roads.
How many curvy sections a random route uses. Ignored once you pick roads yourself.
How far the route detours to avoid re-driving a road. Low = retrace; high = loop around.
How much a road bends — K2 mild, K5 serpentines. Tap a grade to hide it, twice to isolate it.
Reading the map
Every curvy road in range, coloured by grade. Tap one to add it to your route — it turns bold with a white outline. Tap it again to drop it.
The way between your roads. Valico takes the shortest sensible connection, so a blue stretch is getting there, not one of the curvy bits.
The order you drive the picked roads in. The small arrows along the route show which way round each one goes.
How much of the loop is on curvy roads rather than getting to them. 70 % means seven of every ten kilometres are the part you came for.
The number behind the grade, shown when you hover a road: how much it turns per kilometre. 235 °/km changes direction more than twice as often as 98 °/km.
Swipe the route card off either edge, or press its ✕. Your picked roads stay, so you can retune and calculate again.
