"Trail of perfection

Highlight (Segment) • Other

The first 12 km are nice, but once at the top of the col d'aînés, don't follow the trail, the path is no longer cleared at all and a rockslide has partially destroyed it. The comeback single at the end is great though ;)

Justin's Cross

Highlight • Viewpoint

A must-see in the region, easy access via a forest track from Die.

The view over the valley and the Vercors is majestic.

Flow Trail in Parc Naturel Régional du Vercors

Highlight (Segment) • MTB Park

In numerous curves, the trail meanders downhill with a moderate gradient. The less you brake the more demanding! Perfect trail enjoyment !!!!!!!

Pont Rompu - Reserved for bicycles and pedestrians

Small footbridge allowing you to cross the Drôme peacefully. She often takes mountain bikes and gravel bikes to reach Justin.

Die

Highlight • Historical Site

The town of Die is world famous for its Clairette, a sparkling wine served as an aperitif. Nestled at the foot of the cliffs of the Col du Rousset, Die benefits from the influx of the Drôme which guarantees it fertile land cultivated for centuries for the production of wines and aromatic herbs.

Between its architecture rich in history dating back to the 12th century and its preserved surroundings, Die will certainly charm you!

Col de Marignac

Highlight • Mountain Pass

Very nice pass to do outside the busy axes.
Coming from Die, it is an intermediate pass before attacking the climb of the Col de la Croix.
