Guiperreux Toad Crossing

Highlight • Natural Monument

At the edge of this road a pond which forms with the forest which surrounds it a protected natural area.
Each year, during the thaw (roughly from February to April), a "toadstool" is installed on the road that runs along the pond.
But what is a toaddrome exactly? So, it is not a place where one could indulge in clandestine bets on toad races, but a device intended to prevent these poor beasts from being crushed by cars in crossing the road to breed and lay their eggs in the pond on the other side of the road.
Indeed, thousands of common toads, but also frogs and newts, begin their long prenuptial migrations around March each year. They go to the nearest pond or pond to breed. Once their duty is done, they leave the aquatic environment to return to their summering areas where they will spend most of their time feeding.
In order to avoid a carnage of amphibians on the road, a tarpaulin is planted 600m on each side of the road to block their passage. In various places a hole has been made in which a bucket is buried. By looking for a passage all along the tarpaulin, the toad will inevitably end up at the bottom of a bucket. Every morning, volunteers come to collect toads and other frogs and drop them off on the other side of the road.

Le Tartre Gaudran

Highlight • Other

On the borders of Yvelines is Tartre Gaudran, the smallest town in Île de France with its 36 inhabitants (according to the 2018 census) and at least as many horses. Logically, the town hall is also one of the smallest there is ... and there is talk of horse problems.

Grandchamp Estate

Highlight • Historical Site

The royal abbey of Grandchamp was founded in the 12th century by Premonstratensian monks. The abbey was burnt down in 1568 during the wars of religion and the canons almost all massacred. Of the presence of the monks, all that remains is the abbey house and a chapel integrated together in the Domaine de Grandchamp.
This area now houses an agricultural and forestry operation.

Croix de Vilpert Monument

Highlight • Monument

Finding an Egyptian column in the middle of the forest is rather unexpected. In any case, beware, there are not only cycle paths in these woods. The tracks quickly become mountain bike trails.
