The Grand Crêt, at an altitude of 1,702 m, offers a magnificent view of the entire Alps, dominated by Mont Blanc. With a good pair of binoculars, in good weather, and unless I'm mistaken, the Matterhorn (4,478 m) in Switzerland is visible!

The pond in the Bois des Mouilles is a biological reserve. The unpaved path is still accessible to road bikes.

This beautiful, nameless pond is located in the Bois des Mouilles nature reserve. The flora and fauna around the water can be discovered on beautifully laid out paths and platforms.

The trail along the Rhone from Dardagny has reopened - better option than walking through the village. Friendly coffee/food at Cafe Cartigny and excellent goats cheese from Gribi-Wible Farm (courtyard fridge/honesty box)
