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.

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.

in a beautiful forest we arrive there with a magnificent sun which warms up a little

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 old quarries. The bottom rock 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 the oaks, the beeches and the chestnut trees. A feast for the eyes!
