The unguided tours are basically of the park for the hiking trail, etc. Guided tour is only way to see the mammoths. There is a charge for that.
We were there a couple of weeks ago and told there were no unguided tours had to pay admission.
Of you want to see the mammoth you have to pay the $5 for adult or $3 for children
There's no administration unless you do guided tour which runs from $5-$3
