$30 for a car. If driver (or anyone in the car) is 65 or older you can purchase a lifetime, senior pass which is good at all National Parks and Monuments. Cost is 80 dollars. One pass covers everyone in the same car. It's non transferable and they check photo ID when presented.
Senior pass is at $80 for lifetime and worth every penny
If you are over 62 you can get an old age pass for $10 I believe
Fee for a car is $30, which is good for 7 days . There are no daily fees. It's $15 on foot or bicycle
