Montjay Tunnel

Highlight • Trail

Like the nearby Fauvettes viaduct, the Montjay tunnel once served as the old Paris-Chartres railway line. In the middle of the communal forest of Bures-sur-Yvette, it punctuates the straight and rolling line leading to the viaduct.

Old Route of the Limours Aérotrain

Highlight (Segment) • Structure

Interesting crossing of the wood, however beware of the concrete studs that have been sawn in the middle of the track. This can be inconvenient to keep its trajectory. Little room to cross paths, watch out for other cyclists or joggers.

Small bridge

Highlight • Bridge

In the Pont Granval reserve, a small stone bridge crosses a quiet river and offers a picturesque passage. This technical path, with climbs and descents around the river, winds through the heart of unspoiled nature. The rustic and charming stone bridge adds character to your mountain bike ride. The trails around the bridge offer varied challenges with rocky passages and shaded areas.
