Yes! This is a real photo. And it doesn't even do the place justice.
As you might have guessed from the name, be prepared to see some gorgeous dunes at this park. There's one that's notable for how many people climb up it. The press group I was with didn't do that, but we did take in some of the majestic beauty the parks offers. Chances are, you won't be able to take in enough of the deep blue of Lake Michigan in addition to that pure white sand. We were only there for less than an hour, but it's a place I keep revisiting in my head again. If you're in Michigan and have the time, be sure to stop at Sleeping Bear Dunes.
