마레유앙프랑스‬에서 가장 멋진 ‪4‬개의 천연기념물

Very nice trail running outing in the forest 🌳

The fountain is on a small bend, be careful because it is quickly invaded by plants

What is to be remembered from this route is the passage through the Carnelle forest. However, there are too many roads on the Isle Adam and along the Oise. No particular difficulty.

pretty lake hidden in the middle of the forest

High place of pilgrimage (in the region anyway) between the 15th and 18th centuries. The water from this fountain was said to have the power to cure various skin diseases (scabies for example). This pilgrimage ceased shortly before the French Revolution.

A 3-meter-high isolated menhir, made of sandstone, with a typical shark's fin shape, suggesting that a part has been broken. Accessible by walking along the wood in the field, it is visible from the field or the woods.

This funerary megalith dates back to the beginning of the Neolithic period! It is the largest and most famous of all the covered alleys in the Paris region, which has become the archetype of burials associated with the Seine-Oise-Marne culture. All the slabs are in Fontainebleau sandstone, several outcrops of which are visible on the hillside.

Lac Bleu is one of the two bodies of water in the Carnelle forest. On sunny days, its name takes on its full meaning. But there is another reason for the name of this lake from ancient quarries. The rock at the bottom is a mixture of gypsum and marl. The color is changing due to algae, but originally it is deep blue. Around the lake, one can appreciate oaks, beeches and chestnuts. A feast for the eye!
