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."

Very beautiful natural lake of glacial origin in the Chartreuse. The tour of the lake is about 17 kilometers through forest and fields, and allows you to admire the landscape from all angles.

Arriving from Cessieu, I made a small detour via Voissant then the remaining 4 km to the Col des Mille Martyrs. Easy climb, no cars on this early Sunday afternoon and a very beautiful forest upon arrival. Bucolic viewpoints as a bonus during the climb. The descent to Saint-Geoire-en-Valdaine is perfect. Super rolling surface and moderate slope allow you to reach 50 km/h effortlessly. Paradise exists, it is in Chartreuse.
