Twisty routing

Curvy roads on a slider

Every destination has a fast way there. ArcRoute gives you four, Direct, Balanced, Twisty and Wild, and shows the riding time under each before you pick.

The plan sheet with the curviness slider on Twisty and a ride time under each of the four steps, over a route from Zell am Ziller to Bad Tölz
  • Four steps, Direct to Wild. Pick how twisty the ride may get; the riding time for each step sits right under it.

  • A score on every road. Every drivable road in twenty-seven countries, rated by how much it turns, not only the famous passes.

  • Good stretches, marked. The Twisty chip marks the curvy roads near you, and one tap rides a stretch end to end.

The fastest way there is rarely the best one. ArcRoute finds the one worth riding, and tells you in minutes what it costs before you go.

How it works

How ArcRoute finds the bends

A slider to say how many, a score on every road to know where they are, and a map layer with the best runs.

Four steps, one honest number under each

Direct is the fastest way there. Balanced, Twisty and Wild bend the route toward the roads that keep turning.

  • Time under every step. Pick by the day you have, not blind.
  • Wild cannot invent curves. On the plains the steps sit close; in the mountains they spread.
  • Same rules at every step. One-way streets, turn bans and closures count at Wild as at Direct.

Scored across the whole network

Every drivable road in twenty-seven countries has a curvature score: how many degrees it turns per kilometre.

  • 102 million road segments. From Britain and Ireland to the Balkans, Iberia and Morocco.
  • Skip what you do not want. Highways, ferries, tolls and closures off with a tap.
  • Stops on the way. A café is an exact stop; a dropped point only shapes the road.

Twisty roads: the good stretches, marked

Tap the Twisty chip and the curvy stretches nearby appear as pins, each sitting in the middle of its bends.

  • Named by how curvy it is. Curvy, Very curvy or Wild, with length and bend count.
  • Whole roads, at least 2 km. One hairpin or one long sweeper does not make the cut.
  • Add one mid-plan. It drops into the ride as one thing to ride through.

FAQ

Questions about twisty routing

Straight answers on the slider, the score and where it works. The support page has the rest.

All questions and support

How is curviness measured?

By how much a road turns per kilometre: the bends inside each road segment are summed from the map geometry, not taken from ratings or reviews. That is why a short, tight stretch can score higher than a long, flowing one, and why the score is the same kind of number everywhere ArcRoute routes.

Does a twistier route take much longer?

That depends on the land you ride through, which is why the riding time sits under each slider step before you choose. In the hills Wild can double a ride; on the plains it may add ten minutes, because there is nothing to bend toward.

Can I still avoid motorways and tolls?

Yes. Highways, ferries, tolls and known closures each have a toggle, and they apply at every slider position. Direct with highways off is a fair way to get somewhere quickly without the motorway. Closures are Czechia only for now.

Can I save a twisty route for later?

Yes. Save the plan to your rides and navigate it in spring, or reverse it with one tap to ride it home the other way. Planning a route does not record it; the heatmap fills in only from rides you record.

Where does twisty routing work?

In the twenty-seven countries ArcRoute covers. All of them end to end: Albania, Andorra, Austria, Belgium, Bosnia and Herzegovina, Croatia, Czechia, France, Germany, Hungary, Ireland, Italy, Kosovo, Liechtenstein, Luxembourg, Montenegro, Morocco, the Netherlands, Poland, Portugal, Romania, Serbia, Slovakia, Slovenia, Spain, Switzerland and the United Kingdom. The coverage page shows each one with its roads.

Does planning need a signal?

Yes. Planning and rerouting are computed on ArcRoute’s routing server, so they need a connection. A saved ride replays from the phone afterwards, spoken turns included, without one.

Is twisty routing an extra?

No. One subscription unlocks everything, the slider included, and new subscribers get the first fourteen days free.
