How do you get a senior pass for national parks

Any National Park or Monument will have senior passes. You can also order them on-line from any National Park site.

You can buy them at the entry gate when you visit the park.

Go to national park or do it online

You can go to any of the RIM's and you can buy it from there

I have no experience with buying senior pass unfortunately but we bought annual pass for all the national parks which is great value.

They are available at any of entry gate that charge access to the park

You can buy it at the entrance booth to the national park.
