The cave was first entered by the family Casteret (Norbert Casteret, his mother, his wife, and his brother) in July 1926 when they explored most of the main passage. He and his wife returned in September 1926 when they achieved the through trip.[1][6] The Salle Maude was discovered and explored in August 1950 by Casteret and his daughters Maude and Gilberte.[1] The third entrance, the Puits Florence, was first descended in August 1975 by the Club Martel.[7]
