“Best mine tour!”

Reviewed July 16, 2014

Thanks to our amazing tour guide, David, for the super informative and interesting tour. He had my 5 and 7 year old boys eager to learn more! There were about 25-30 people in our group tour and amazingly David could talk to all of us by name! A great tour guide is more than half the actual tour itself. And the Gold Panning is a must for the kiddos. They loved it :)
