In summer

High fir trees, the scent of undergrowth, characteristic peaks - you've arrived in the Chartreuse, a mysterious and bewitching mountain range. To be precise, you’ve arrived at Col de Porte. At the heart of the Chartreuse Regional Nature Park, the unique and unspoilt Col de Porte lies at an altitude of 1,326m

It is surrounded by the famous Chartreuse peaks: Chamechaude, the highest peak in the Chartreuse, La Pinéa with its spectacular 360° views and Charmant Som. Charmant Som is perhaps best known for its accessible mountain pastures and the Auberge du Charmant Som, famous for its fondues and blueberry tart.

At Col de Porte, you can also enjoy a lunch or dinner in one of the two restaurants: Les 3 Sommets  and le Cartusia .

We recommend that you make this a nature stop during your visit, to take in the environment and the many sporting activities on offer. Col de Porte is easily accessible from Grenoble by public transport for an eco-friendly holiday.

Extra tip

Make the most of this peaceful environment during the low season or during the week.

The Chartreuse mountains at your own pace

Hiking is the ideal way to discover the mountains

From Col de Porte, different hiking levels await you. You can discover the mountain on easy trails from which you can admire the Chartreuse scenery, such as Le Sentier des Géants. It's a 1.6 km loop to admire the richness of the area: the Chartreuse resinous trees, renowned for their great expanse and classified as PDO Bois de Chartreuse, the pastures where alpine cows graze, and the flora and fauna of this specific ecosystem. More technical peaks, without being high mountain, await you for an ascent with a greater difference in altitude, such as the climb to Chamechaude at 2,082m high. Majestic scenery is guaranteed at the finish!


Hiking in the Chartreuse

Shared space, preserved space

  • I stay on the trails, I only touch with my eyes
  • I take my rubbish with me
  • I pay attention to fences and grazing animals
  • I don't make a fire
  • I keep my dog on a leash
