Can I purchase a National park senior pass at your location with the visitor center being closed? I am pressed for time to mail.

I want you to know the window is open. That's how I purchased my yearly pass.

I believe you can but you should call for hours.

There is a Pavillion that have envelopes. It is Honor System at this time as there are no employees in the building to sell the permit

Was there a few days ago. They have something set up in the other building to purchase passes. Cash only.

I don't believe so but you can always call and try. I believe you can register online though.

I do not believe so since, as you stated, the visitor center is closed.
