The best way to reserve a campsite in a national park (not all national parks have campgrounds where people can reserve a site) is Recreation.gov. Besides campsites, it will also let people sign up for other things.
I made use of the reservation site in November 2015 to reserve a campsite at the North Pines Campground in Yosemite National Park in April 2016. I found out the date and time the reservations start and I was ready on that date and time by setting it on my cell phone's calendar. It was a good thing I did as sites were gobbled up in short order.
The features I like the most is that a map of available (and taken) campsites is provided along with a photograph of each site. This way, people can see what's available and see what the site looks like without blindly selecting a site and finding later on arrival that the site is too short for their 40' motorhome.
