La Corraterie is a narrow rocky ledge and cliff path on the west flank of Mont Salève (the so-called “Balcony of Geneva”) in Haute-Savoie (France). From here, you have breathtaking panoramic views of Lake Geneva, the city of Geneva, and the Jura Mountains. Highlights along the path besides the view ;-): ⭐ The passage cave Grotte d'Orjobet. ⭐ Trou de la Tine: An impressive natural rock arch and sinkhole formed by erosion in the cliffs of La Corraterie. ⭐ Numerous climbers can be observed on the vertical limestone walls. And here is the story behind the flag on the mountain path: It is not the Swiss flag, but the coat of arms of Savoy (meaning no white cross, but the bars extend to the edge). It all began in the late 1960s. American students from the nearby Adventist campus in Collonges-sous-Salève climbed the steep rock face after a night of revelry. Since the mountain offers a direct view of Geneva, they were firmly convinced they were in Switzerland. They painted a huge Swiss flag on the rocks. However, Mont Salève is geographically located in France (Haute-Savoie region). The local French residents found the Swiss flag on their mountain to be an affront. Local activists climbed up and painted over the Swiss cross, turning it into the coat of arms of Savoy (Cross of Savoy) to emphasize the French-Savoyard affiliation. To this day, unknown individuals (mostly from Geneva) regularly climb the wall at night to shorten the bars and turn the Savoy coat of arms back into a Swiss flag.

A beautiful view of Geneva, or rather, its clouds.

Le Trou de la Tine (Trou of the Tine Cave) was formed by erosion on the flank of Mont Salève. It is a deep, sunken hole shaped like an open-topped barrel ("Tine" is an old dialect term for barrel, "trou" means hole). The cave's ceiling has collapsed due to erosion, revealing a natural "barrel" with a side opening. One can walk into the "barrel" through this side opening.
