The Plain-de-Saigne pond is a small artificial lake located in Montfaucon. It's a great place to picnic and admire the reflections of the sky and trees on the water. You can also learn about the history of the lake, which was once home to a mill and peat extraction site.

The Sorne has dug itself deep into the rocks and today roars between almost vertical walls through the wildly romantic gorge. Numerous springs flow into the Gorges du Pichoux. Are there actually 1,000 sources, as the name “Pichoux” translates to? At the end of the gorge, Lac Vert shines like an emerald in the most wonderful shades of green - a fantastic place for your picnic. The Gorges du Pichoux is located on the road between Bellelay and Undervelier. By public transport or by car go to Sornetan, Le Pichoux.
