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.

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.

This bucolic path runs along the Stors marsh nature reserve. The ground quickly becomes muddy in bad weather and the days following the rain. That said, the setting is beautiful along the rock faces. For the rest, it's a fairly easy single.
