The reception chalet opens 30min. before the start of the first guided tour. You are requested to present yourself at the reception at least 15 min. before the start of the tour.
Water integrally makes part of the visit. It may be that the water level of the river makes it impossible to organise the boat ride. In such a case, the guide will take you for an extensive visit of the upper floors of the caves at the attractive price of 5.5€/Ad and 3.5€/Ch.
For safety reasons, only front baby carriers will be allowed in the caves. You can leave your pushchairs in complete safety at the reception chalet.
The average temperature of the caves is 12 °C throughout the year. Make sure you bring a jumper or a jacket. Sturdy walking shoes are recommended.
