No special access issues
Park on one of the parkings shown. All basically works well.
1. Park on the north parking, walk with Chemin du Rocher de la Reine until you can basically see the rocks.
2. Park as for Drei Zinnen/Rocher de la Reine walk along the ridge and approach from above.
3. Park as for Bois Rond/bois rond auberge. Walk along Chemin de l'Auberge until you reach a crossing, walk staright over and up the steep hill. At the top, take a right and walk about 150-200m and then down to the left to reach the sector Petite Reine. For other sectors continue on the ridge.
