To the north of Questembert, the town of Molac is perched on a hill overlooking the Valley of Arz. The town's architectural heritage reflects its history, which is thousands of years old. The trail heads toward the River Arz and takes the Voie Verte (Green Lane), the old railway. It crosses the Grées (shale-like hills) of Lindeul. Finally, it penetrates the vast forest of Lanvaux. Please follow the yellow marks.
