Tipping point on the ridge between several valleys. Very pleasant climb from Saint Julien sur Bibost.

Even using the cycle lane I don't feel safe: heavy road traffic and a circuit popular with motorbikes which overtake you at very high speed.

A very beautiful site with a magnificent view at this crossroads of many roads. However, can we really speak of a pass because it is basically a cross, but this place has the whole profile to be one. In any case what is certain is that you have to go up there!

A rolling pass but with a lot of traffic including some heavy goods vehicles. A wide cycle lane allows cyclists to climb in safety. However I advise to take another pass to make the junction, for example to use the road between the cassettes and the pestle on a false uphill slope.

Pretty long pass on the Tarare side with a constant slope around 5%. Delimits the watershed line between the Rhône and the Loire. Do not hesitate to climb to Mont Boussuivre by extending a few hundred meters and climb to the top of the Matagrin tower to enjoy a magnificent view of the whole region.

A small pass to do from Tarare, or Valsonne. Not very hard percentages and quite short. Rural landscapes surround us on the climb. Note a beautiful little road that connects the Col de la Croix Paquet, Col du Pilon with beautiful views but a coating that is not incredible so you can enjoy the landscapes.
