It's a National Park, so you pay for a park pass. Depending on what type of pass you want, (ie, just one park, multiple parks, annual, etc.) determines the price. You can find park pass pricing at the national parks website. https://www.nps.gov/planyourvisit/passes.htm
We just went it was 30 a car
They're all different Grand canyon is $25 for one car does it matter how many people. They do sell a senior citizen pass I want you to have one of those it's good for life for all the national parks.
We were a short time ago, and because of the shutdown it was all free, even the shuttle buses. Maybe if you're lucky, they still have not restored the payment. To enter the park with the car, it costs 35D if I remember correctly.
