Signal de Saint-André

Signal de Saint-André is a mountain summit in the Monts du Lyonnais located at 934 meters in elevation. In clear weather, it offers views reaching toward Lyon, the Alps, and the Pilat massif across the landscape.

In 1744, cartographer César-François Cassini established a geodetic marker at this summit. This was part of his assignment to create the first detailed map of France.

The summit has a small outdoor amphitheater with seating for about 30 people, where local events and educational talks happen regularly throughout the year. This space brings together visitors and residents to share knowledge and enjoy performances in an open-air setting.

From the parking area on road D113, an 800-meter uphill walk reaches the summit following the marked GR7 hiking trail. The path is clearly marked and passes near the village of Saint-André-la-Côte.

The summit houses one of 53 French National Frequency Agency stations. This facility is used for radio spectrum control and goniometric location measurements.
