Age Requirement: 62 years old – US citizens or permanent residents 62 years or older are eligible for a Senior Pass.
U.S. National Parks offer a senior discount on the Senior Lifetime Pass for adult customers 62 and older, which includes an $80 lifetime pass and 50% off on some amenity fees charged for facilities and services such as camping, swimming, boat launch, and specialized interpretive services.
So I can get two passes for $20 each that last our lifetime? No entry fee upon arrival, yes?
It seems like there’s a bit of confusion regarding the Senior Pass options. To clarify, the $20 option is for the Senior Annual Pass, which is only valid for one year. If you’re looking for a lifetime option, the Senior Lifetime Pass costs $80. This is a one-time purchase and is valid for your entire lifetime. While both passes provide access to participating federal sites without additional entry fees, it’s important to note that the $20 pass does not cover a lifetime, but only one year. To get lifetime coverage, you would need to purchase the $80 Senior Lifetime Pass. Check our National Parks Senior Discount page for more!
