プレミリューの峠・トップ5

Officially referenced pass and completely passable by road bike!

A legendary climb to do in your life

Not included in the four access routes to the Col du Grand Colombier, this climb is nonetheless formidable. The numbers speak for themselves: fourteen kilometers at an average 9% gradient and one section at 22%. Called the Directissime, this variant is worth knowing.

Pass at 929 m altitude, ascent from Virieu-le-Grand or Tenay.

Regular climb with very few cars all year round and nice viewpoint over Mont Blanc and the Alps on good weather days.

Superb discovery, this Col du Ballon deserves to be a little better known, but not too much anyway 😁 What a moment, from Tenay, the first part is hard, but never too hard, the landscape is nice, the road so peaceful... The meter indicates portions beyond 10%, and the steepest kilometer indicates 9.9% , but it's nice enough to do quietly. The second part is much less steep, still on a small, very narrow road up to 2km from the summit, but no traffic, good condition of the road, and the descent to Virieu is on a wide road in very good condition too 😁 It was a very nice discovery, to be made again with less heat 🥵!!!

The pass, located at an altitude of 1,050 meters, offers you a magnificent view of the Alps and the Rhône valley. Like most of the peaks in this region, it sometimes allows you to see Mont Blanc.

The Col de Ballon is 14.1km long with an average gradient of 5%, although there is a slight descent at the 11th km which reduces the overall average gradient.
