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.

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.

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.

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!

The Blue Lake, like the small pond located a few dozen meters away, has been built in old marl quarries, which give the water a bluish color. For this reason, they reach a depth of 20 to 30 m and swimming is prohibited there for safety reasons. On the other hand, you can go fishing there. The ponds have replaced the quarries, and the presence of green marls, which color their bed, explains their astonishing variation in color. Going from turquoise blue to emerald green, depending on the depth, the time of day, the intensity of the light.
