We just visited again (May 2015) after initially seeing the monument about 15 years ago. I was concerned after reading the disparaging review above, but our experience was vastly different. We were charged a small fee upon entering (especially small since we were driving a motorhome and towing a car). We also rode the bus to the base of the mountain, and it was only $12 for the 3 of us. The driver was fabulous, stopped several times for pictures, answered all of our questions, and pointed out many other things of interest.
For those who think they can see all there is to see from the road are truly missing out. Without learning the history behind this undertaking you won't understand what a monumental commitment this family has undertaken. Crazy Horses's head is so large that all of Mt. Rushmore can fit inside it, and it was carved out of the mountain by one man. No government teams and no government money. Is there any question why it's taking a long time? As of now, there are only 7-10 people working on the mountain each working day.
Crazy Horse can use our help. They are completely funded by donations. It was fascinating to see how much progress has been completed since we first experienced it 15 years ago. Now, with new technology, this sculpture could be completed in the next 25 years! Watch the video, read the posters and experience each stage of completion.......it's fabulous.
