For only $10, U.S. citizens and permanent residents age 62 and older can purchase a lifetime Senior Pass to U.S. national parks. Another $10 is required to process the application. Total cost: $20.
When you consider it costs $80 for a one year national park pass, this becomes quite an attractive offer.
There are a few things for which the pass will not pay: fees charged by park concessions are not covered; same for some recreation permits you might need in certain parks. Those with questions about Senior Pass will generally find that even when the exemptions are noted, this is still something that will pay for itself with one visit to a park that charges admission.
