The climb from La Terrasse to reach the plateau has a good steady 9％ gradient for 7 kms, then the gradient drops to reach the Col de Marcieu. The view of the Grésivaudan valley and Belledonne from the plateau is nice.... read more

The climb from La Terrasse to reach the plateau has a good steady 9％ gradient for 7 kms, then the gradient drops to reach the Col de Marcieu. The view of the Grésivaudan valley and Belledonne from the plateau is nice.

La montée depuis la Terrasse pour rejoindre le plateau a une bonne pente de 9％ régulière pendant 7 kms, puis la pente diminue pour rejoindre le col de Marcieu. La vue sur la vallée du Grésivaudan et sur Belledonne depuis le plateau est sympa.
