Does the car, RV and cycles part of the payment or do I have to come whith one of those three things?

I'm not really sure what you are asking. You have to pay weather you drive in or walk in.

It's 20.00 dollars for a carfull pretty much to help pay for the animals if you want to go see the bears pay to see the bears.

There is literally nothing around there if you walk it's going to take you a long time.

20$ per car load of people

20 for any of those you mentioned. Family I am thinking.

Its 20 dollars for a car load of people

I would expect that they'd charge you $10 for admission if you walked there.

Take your car.
