This site is exceptional because of its huge galleries and the profusion and quality of its aragonite concretions which look like snow crystals due to their white colour and shape. The Lake Room in the damp area has superb concretions. The cave, opened in 1997, is strictly protected and the number of daily visitors is limited (booking is therefore strongly advised).
