Grottes de Médous, Natural cave system in Asté, France
The Médous cave system contains two main sections: the lower Dry Gallery and the upper Wonder Gallery, featuring numerous mineral formations and an underground river.
Three local speleologists discovered the cave system in 1948 behind the Médous springs, leading to its development and public opening in 1951.
The cave's name originates from Latin 'Mellis Dulcis', meaning sweet honey, potentially referring to the spring water or religious significance of the location.
The cave operates seasonally with different schedules: April to June and September to October from 9-11:30 AM and 2-5 PM, July to August from 9 AM-12 PM and 2-6 PM.
Visitors experience the cave through a guided tour that includes a boat journey on the underground river, connecting to the larger Adour river system.
