A small observation deck at the top of the religious site. Unfortunately, the surrounding area would benefit from being cleared of trees to fully appreciate the view, as the panorama is limited by vegetation. It's best to visit in winter to be less bothered by the foliage.

Very pleasant pass to climb, not too steep a slope, well marked all the way.

Arriving from Cessieu, I made a small detour via Voissant then the remaining 4 km to the Col des Mille Martyrs. Easy climb, no cars on this early Sunday afternoon and a very beautiful forest upon arrival. Bucolic viewpoints as a bonus during the climb. The descent to Saint-Geoire-en-Valdaine is perfect. Super rolling surface and moderate slope allow you to reach 50 km/h effortlessly. Paradise exists, it is in Chartreuse.

A religious monument coupled with a magnificent observation platform. A must see.

A very interesting castle that looks more like a fortified house. That said, it has a working moat and drawbridge!
