If you have a national parks pass it covers the entry as it is part of the NPS. Otherwise it is $20 for a car. $10 for a bike.
The fort is free to visit Lisa. The national park has a cost for the week.
Also offer military discount. 20 dollars is good for the week
$20 for the car.
My husband and I were there last week and it was $20 for us. They do offer a senior citizen discount, but I'm not sure how much. It's well worth the price!
