Enter the NPS senior pass number where it asks for a card code while making your reservation online and it will give the 50% discount when paying for your stay. We just went 6-30-19. If paying in person at campground, put your code on envelope and pay 50% of the fee.
Yes the pass is good for camping
If you are referring to the National Parks Senior Pass, I don't believe so. The campgrounds are not considered National Parks. I would call the phone number listed and ask someone directly for actual verification.
