Arrived midday Wed. There were about 6-7 places available, by 5 pm it was nearly full. Very quiet night. 13 euro + water cost, vehicle recognition, barrier goes up on entry and you go to machine on exit, put reg in, and pay. There’s a disposal area just outside with paid water if you only require services. Easy 15 min or so walk into town Etretat is a nice seaside town and is well worth a visit.
