By road or trail


Do you want to cycle Alpe d’Huez, le Croix de fer, Glandon, Sarenne or Galibier? You can do them all from Chalet 800 in Oz village.

Besides the well-known mountain passes there are a lot of other beautiful and challenging mountain roads to discover.

Do you like a challenge? Then you are ready for La Marmotte, a famous sportive where you will climb four legendary mountain passes. Keep in mind that the mountain passes are not open all year round because of their altitude and can be closed due to snow cover. The best period to cycle this impressive sportive is from June to mid-October.

At the Chalet we have information on all the mountain passes for you to explore and we made a selection for you to discover right away.



The region of the l’Oisans is also very good for people who want to mountain bike or downhill. The region has a lot of very steep cross-country routes and challenging single tracks to descent from. Many mountain bike events also take place in Oz Station.

From the Chalet you can take your MTB on the free bus to Oz Station and from there the gondolas take you to Pic Blanc in Alpe d’Huez. The gondolas are open in July and August.
