We booked onto the French tour thinking that as a cave, there would be lots to look at (as per a wonderful previous French speaking tour around Grottes de Lacave) and so the language barrier would not be an issue. The lady at the booking desk happily booked us onto the French tour knowing we spoke no French and didn't mention the necessity of waiting for an English tour. Unfortunately, the tour was really a lecture, 25 mins of which took place in a museum style dark room with no writing (and as it was jam packed you couldn't see the exhibits). The guide talked, no time was given to look at anything. If it had been in English it would have been pretty dull too. We were then taken into the cave part, which as we already knew was fake but I could live with that. It was very small and so the remaining time was spent in the one cavern, while she quickly talked away. Even the French visitors were talking amongst themselves as their attention waned. In total it was 65 min rather than 45. I've never rushed out of anywhere so quickly in my life! You could argue I shouldn't have booked a French tour but if there was something more to see this wouldn't be an issue, besides which the other cave gave little leaflets in the most popular languages to help, even though it wasn't needed. I wouldn't even bother with the English tour, there are so many other fascinating (and genuine) caves to explore.
