Grand Colombier, ENS de l'Ain

The Sur-Lyand plateau is located in the southern part of the Massif du Grand Colombier, at an altitude of 1,250 metres. For more information, see the ‘Sur-Lyand’ article. Crossed by the GR9, the Grand Colombier offers a wealth of opportunities for walking, horse-riding and cycling.

The Grand Colombier was awarded the ‘ENS’ (sensitive natural area) label by the Department of Ain in 2017. The sites awarded the ENS ‘sensitive natural areas’ label are natural and landscape treasures of the Ain department, managed in such a way as to preserve the biodiversity within them and are developed so as to be able to welcome the public (with certain exceptions due to the fragility of the environments).
