The accident occurred on Saturday around 1:45 pm at Parc Saint-Paul, the park said in a news release. Authorities in Oise confirmed the incident to CNN.
The woman, 32, fell while riding the Formula 1 Coaster. Emergency services were called immediately but were unable to resuscitate the victim, who died on the scene, the park said.
Another deadly incident occurred on the same roller coaster in 2009, park president Gilles Campion told CNN.
The Formula 1 Coaster is one of 45 rides at the park. Children at least 4 feet or taller can ride the Formula 1, described by the park as a family friendly attraction.
The section of the park where the roller coaster is located was closed to the public after the accident, according to the news release.
Parc Saint Paul reopened on June 6 with coronavirus guidelines set in place, including a mask requirement and social distancing measures.
