You can stand here just fine. Please note: Chateau Peyrepertuse is at least an hour's walk from this parking lot. The parking lot at the castle can be reached by camper bus (right before the last hairpin), larger camper can park a little earlier next to the bus parking on the way up (is indicated). On the castle grounds, first a long and very uneven path uphill, mountain/hiking shoes and fitness recommended. Gorges de Galamus prohibited >2 meters wide.
