Lake Paladru is very popular in the summer, especially on weekends. Swimming is possible; there's a small, well-equipped beach.

Personally, I don't really like going through this roundabout. Coming from St Niziers, you can turn left before, to go towards Villard.

Lans is a very pretty village in the Vercors, the resort is at Côte 2000, a little higher up. It's not necessarily the best starting point for a bike ride. We prefer Villard de Lans, which offers a multitude of routes.

Perhaps the most beautiful road in the Vercors? In any case, one of the wildest with its tunnels and narrow passages.

During Holy Week, Christians commemorate the Passion of Jesus Christ, beginning with the triumphal entry into Jerusalem (Palm Sunday), the Last Supper (Maundy Thursday), and ending with the arrest, condemnation, and execution (Good Friday), which then culminates in the Easter Vigil with the celebration of the Resurrection, the climax of the church year. The biblical accounts of the New Testament that describe these events paint a very nuanced picture of the Apostle Peter (Saint-Pierre), to whom the church of Charavines is dedicated: on the one hand, he is a determined disciple of Jesus, but also not free from human weakness and fear. In the Garden of Gethsemane, he (like the other disciples) falls asleep when Jesus turns to God the Father after the Last Supper and asks the disciples to pray as well. And after Jesus' arrest, Peter denies three times that he even knows him. But he also weeps over his weakness and, upon encountering the risen Christ, affirms his love and loyalty to him. His real name is Simon, but Jesus gives him the name Peter (which means "rock") on which the church is to be built and gives him—according to the account of the Evangelist Matthew—the "keys to the kingdom of heaven."

A small village in Isère nestled at the foot of the Vercors, Rovon preserves several discreet monuments from its rural past. There, you'll come across a renovated Romanesque church, old stone farms, and a few wayside crosses. A village to discover along its narrow streets and trails.

A very popular lake to visit during the summer months when the lake is quite refreshing. Every year, there is a time trial around the lake.
