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!

The Col de la Croix de Mazieux from Saint-Forgeux is 6 km long with a total drop of about 298 m. The average gradient is 5% with maximum gradients of 9%, however the first part of the climb is steeper and flattens out after 4km.

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.

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.

A real raider! 2 km at 10% roughly. On the Valsonne side it's harder because the long straights with 12% are very painful for the legs. The view at the top is really pretty over the valley of Valsonne and Tarare.
