Col de Sarenne (1999m)

Either a route as an extension after reaching the summit of the Alpe d’Huez or an alternative way up to the resort other than the famous 21 bends.

Continuation from Alpe d’Huez

The Col de Sarenne continues past Alpe d’Huez for 9km on a narrow undulating road, topping out at 1999m. It feels rather remote partly because it can be very quiet due to its lack of passing civilization and poor road surface in parts (not a surprise considering it makes up part of the longest black ski run in Europe) but make no mistake it is one of the most beautiful routes in the area and really allows you to ‘be at one’ with your bike and the road.

Once at the top of the Col de Sarenne there is a huge switchback road descending to the Barage du Chambon at the foot of Les Deux Alpes.

Alternative route to Alpe d’Huez

The route can also be tackled the other way around from the Barage du Chambon; it is a big climb, but it does mean that you descend the 21 bends of Alpe d'Huez which is always a thrill. Firstly make your way to Bourg d’Oisans and head up the valley towards the Col du Lautaret before turning up the Vallée du Ferrand towards Besse. From here you can start to tackle the Col de Sarenne.

Once you breach the top of the Col there is a short descent to a road along the Sarenne valley. The route continues along this road for 9km at a height of approx 1900m before arriving at the back of the village of Alpe D’Huez. The whole loop from Allemont is 60km with 1500m of climbing. This is another good option for testing out your legs before taking on harder cols, such as the Col du Galibier or the Col de la Croix de Fer.
