Absolutely.
The America the Beautiful Passes (there are several kinds) are available to provide free or discount admission to National Parks and other FEDERAL facilities (and a few states actually honor them too!) However, as noted below a non-citizen cannot purchase a Senior Pass which gets you half off on camping in addition to reduced or free admission. However, since many national parks charge $20 or more for admission now, its a no brainer to buy a regular Annual pass if you intend to visit several National Parks. Some National Parks such as Mt Rushmore do not change admission, just a parking fee, however the Badlands NP charges $20. I made good use of my Permanent Senior America the Beautiful Pass the first trip I made in 2017 and since then
While
you can purchase the Annual Pass online, it is probably better to wait until you go to enter a National Park that charges an entrance fee and purchase it at the gate.
THIS is a list of all the places passes may be purchased. Not all locations sell all versions of the passes, so check carefully. I bought mine on my 62ed birthday at the Project Office for the West Point Georgia Dam and Reservoir. It was still $10 but about three months later the price went to $80.
Who qualifies for the Senior Pass?
U.S. citizens or permanent residents who are 62 years or older. (You must have turned 62 before you can buy the pass).
NOTE: Owning property or paying taxes in the U.S. does not automatically qualify you for a Senior Pass. You must be a permanent U.S. resident, or a U.S. citizen with identification such as U.S. Driver's License, Green Card or U.S. Passport.
Who qualifies for the Annual Pass?
Anyone 16 years or older may purchase the pass; children under 16 are always admitted free.
Where can I use my Senior Pass?
Where can I use my Annual Pass?
Please contact a site directly if you have a question about pass acceptance and fees.
The Forest Service, the National Park Service, Fish and Wildlife Service, Bureau of Land Management, Bureau of Reclamation, and US Army Corp of Engineers honor the Annual Pass at sites where
Entrance or Standard Amenity Fee(s) (Day use fees) are charged.
In addition, the Tennessee Valley Authority may honor the Senior Pass for entrance or camping discounts.
Pics below are two COE or USACE campsites I have been in. Left Tailrace Campground below Lake Sharpe Dam, Ft Thompson SD, and White Oak Creek Campground (Alabama side of the lake) on Lake Walter F George (locally known as "Lake Eufaula" which is NOT its proper name) anyhow, on the Chattahoochee River.
Reservations for COE campgrounds are made on Recreation.gov
This is the official website for the COE lakes and recreation areas, where you can select by state and get a chart of locations and various facilities available at these locations. The book Kirk referenced above is derived from this website.
