In my opinion, this is a terrible road for a road bike. I don't enjoy cycling back, but the "view" from my perspective isn't worth the ride, as most of it is trees and you only get a brief glimpse of the lake or the valley below, not to mention the Salève. The road is already very bad a few kilometers past Thoiry and only gets worse. I continued past the viewpoint, hoping to eventually reach a decent paved section. However, that didn't happen until the descent to Crozet. Of course, this isn't a problem on a gravel bike or mountain bike. I was glad I didn't get a flat tire.

Even though the public no longer has direct access to the experiments at the Large Hadron Collider (LHC), we found the visit to CERN extremely interesting. During the tour we booked, we were captivated by the lively explanations of a British scientist who was involved in the discovery of the Higgs boson and therefore had authentic information to offer. In addition to the well-designed museum, we even got a glimpse into the control room of the Atlas experiment. Conclusion: a very interesting excursion for those interested in science!

Rainwater retention basin transformed into a beautiful pond with reed beds. The pond and the reeds attract many birds. Some of the birds you can see in the area include the Southern Bittern, Little Bittern, Spotted Rail, Water Rail, Little Grebe, Reed Warbler and Reed Bunting.

Very nice hike. Perfect with 2 children and a dog. However, there is no sign indicating that we are entering a nature reserve, just a sign when we leave.
