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.

In the English Garden, the flower clock is made up of more than 3,000 colorful plants. This horticultural mosaic requires special know-how, admirably implemented by the green spaces services of the City of Geneva. The plants of the clock are changed four times a year, giving life to a mosaic per season.
