"A bit difficult for older people or people who are overwhelmed with small spaces since you have to crawl to get from one side to another, crawl... they should notify you before buying tickets.
Otherwise great! A beautiful and fun experience."
"Great visit to our geological heritage. The unbeatable attention with a guide who explained the visit perfectly well. The facilities are also phenomenal, as they have a restaurant and menu. Highly recommended for groups of friends and families. Although I went alone."
