Grand Colombier Mountain Pass

Open today
Espaces Naturels Sensibles


It may seem a little insane, but you can’t beat the sense of achievement you get at the very top!


Grand Colombier is the highest mountain peak in Bugey at 1,534 metres (5,030ft). A challenge for even the most experienced of cyclists, the pass grabbed the attention of Tour de France organisers and will form part of the race’s route once again this year. An enticing challenge for hikers and walkers with a panorama guaranteed to take your breath away.

Tour de France on Grand Colombier Pass in 2016

Protected natural land for miles all around

Lynxes, chamois, woodlarks, orchids, narcissus and globeflowers… Here you can expect to see a wide range of wildlife and vegetation in a natural setting now protected by the Sensitive Natural Areas classification (ENS in French). The site offers a 360° panoramic view of:

  • Mont Blanc and the Alps,
  • 3 alpine lakes: Lake Bourget, Lake Annecy and Lake Geneva,
  • the Rhone River.

You can visit the pass by car, along a road promising spectacular views from Culoz or Anglefort on the east side, or from Virieu-le-Petit.

On foot, over 100km of hiking trails lead up to the summit and continue along the ridge where the views will really blow you away!

The Tour de France is back on 9th July 2017!

For the 4th time in 6 years, the 9th stage of the competition will run from Nantua to Chambéry. But it’s no mean feat, covering a distance of 18km and with slopes ranging from 14% in gradient to 22% in the toughest parts, the climb is classed hors catégorie (beyond classification)! Nonetheless, athletes still meet here every Saturday, ready to take on the ascent.

Grand Colombier Cycle Challenge

The road will be closed to traffic on the first Saturday of each month from June to September, so that cyclists can complete the climb, departing from Culoz and ascending on the Anglefort face.

Participants will be welcomed at the summit by the Brotherhood of Mad Cyclists (do you fancy joining the brotherhood?), Bugey Sud-Grand Colombier Tourism Office and the Department of Ain Council with a well-deserved snack!

Survivor’s story:

“What a fantastic but very tough challenge! I really enjoyed the day and all the four faces were very different.” – T.C. on 23rd July 2016
