Col d’Ornon Cycling Guide

A Quiet Oisans Climb with a Descent You Should Respect

What riders are looking for

If you’re planning a cycling trip to the French Alps, the Oisans Valley is often the first name that comes up — usually because of Alpe d’Huez.
But not every ride needs to be iconic, brutal, or crowded.

Many riders search for:

  • a quieter Alpine climb
  • a rest-day ride near Alpe d’Huez
  • a scenic Category 2 col
  • or an introduction to Alps cycling without traffic and stress

That’s where the Col d’Ornon fits perfectly.

Assumptions about the Col d’Ornon

At first glance, the Col d’Ornon looks ideal:

  • smooth tarmac
  • gentle gradients
  • quiet roads
  • beautiful views over the Oisans Valley

From Le Bourg d’Oisans, the north-side ascent is around 10 km, averaging 4.8%, climbing to 1,371 m. It’s been used in the Tour de France (first appearance in 1952) and is officially classed as a Category 2 climb.

Most cyclists assume it’s a relaxed, low-risk Alpine ride.

The reality riders don’t always expect

The Col d’Ornon is beautiful — but it’s not risk-free.

On this very road, my son was hit by a car while descending.
He was fine, but watching it happen as a father changes how you see a “quiet” climb.

The lesson isn’t fear — it’s awareness:

  • cars can carry speed on open sections
  • some corners invite riders to drift wide
  • descending demands discipline, even on calm-looking roads

Oisans Experience, routes, and what to ride next

From the Col d’Ornon, you’re perfectly placed to explore some of the best hidden climbs in the Oisans:

  • Oulles – short, steep, and spectacular
  • Col du Solude – for experienced riders, mixed surface

It’s an ideal base for riders who want authentic Alpine cycling, away from crowds, but still close to legendary climbs like Alpe d’Huez, Croix de Fer, and Galibier.
