This was an amazing experience - never seen anything like it. Well worth it!! Rock formations and history of it that is given by the guide is fantastic! I was hesitant as I was taking a 7 year old and a 1 1/2 year old in to the caves (my sister had her 3 children as well.) I carried the little one using a front pack and it worked well. We were told that there is a lot of bending and small areas to get thru but it was no problem. We were disappointed in the fact that we weren't informed that the gift store would be closed by the time we would be finished the tour which left the kids disappointed that we had to leave without souveniers. Had we been aware, we would have made our purchases before the tour. In any case - worth the drive!
