From Culoz: 18.3 km. D+: 1262 m.
Without a doubt the most beautiful road with these spectacular laces and a remarkable panorama that can be discovered over the first few kilometers above the town. This road is rather irregular and promises important heat in the first 7 kilometers between vineyards and cliffs especially in the afternoon. Halfway along the trail, the slope getseasier in the forest, allowing you to rest a little in the sun before attacking the second part, which is just as difficult as the first. An advice, save some strength for the end.
From Artemare, via Virieu-le-Petit: 15,9 km. D+: 1251 m.
The ascent of the Grand Colombier from Artemare (via Virieu-Le-Petit) is the most direct one. The road can be very straight with an horrendous part at 22% above Virieu-le-Petit…
From Anglefort: 15.7 km. D+ : 1251 m.
The ascent of the Grand Colombier by Anglefort is perhaps the least known but remains nevertheless formidable !
From Champagne-en-Valromey by Lochieu: 12,3 km. D+: 900 m.
This ascent of the Grand Colombier is known to be the least difficult of the four roads. The ascent is composed of several flat parts between its climbs at more than 10% all the same. The last two km, however, offer no rest; the final ramp is steep and often windy.
Grand Colombier is only for cyclists on the second Saturdays of June, July, August and September! In 2024, these carfree cycling days will be held on 8 June, 13 July, 10 August and 14 September.
