I visited this WHS in May 2015. The only way to be able to actually "see" something within the buffer zone of this site is to hike a 30 minute trail, next to the Pont d'Arc, to the closed entrance of the real cave of Chauvet which unlike the one in Lascaux still lacks the UNESCO WHS plaque. However, I decided to visit the replica cave after the very positive experience I had had at Lascaux. I booked months in advance and paid 13 euros for an English guided visit starting at 11:12am ... the punctuality should have already been an indication of the number of visitors (mainly French) who want to visit this WHS. Unfortunately, I thought it was just a misprint so I didn't bother. The ticket clearly indicates to be there at least 45 minutes before so I went there early enough to secure a free parking space in the enormous parking lot and be on time. The number of parked coaches/buses/vans full of Frenchmen was incredible. Many majors and politicians are promoting the replica cave as a symbol of national pride and as a great feat, so I would advise anyone wanting to visit the cave to avoid the French guided tour for this reason at least for the coming year or two. Every 7 minutes a new group is invited to visit the replica cave and a guide describes the main sights and their importance one stop after the next (one group of around 20 people after the next!). The English guided tour was not as packed so I considered myself to be quite lucky on the day. The drawings are incredible and what I liked most were the finger drawings of animals in clay (especially the owl drawing). The bookshop is stocked very well and I bought several books/magazines/first day covers, etc. to further understand the importance of what is marketed as "the first masterpiece of mankind". The museum is very modern with touch screen displays and high tech stuff yet I won't be coming here again anytime soon. I enjoyed my visit but I would prefer the Lascaux experience for a re-visit. Like in Lascaux, photography is not allowed yet I managed to take a quick photo before leaving the replica cave :)
