Thanks to a SUPER accommodating NPS fella, we got site 111 for a couple of nights during the Dark Sky Festival. It's dry camping, which suited us for the short stay. We were stoked to be next to a little road that led to a nice birding spot and the little airport. Super charming...

Until the generators kicked on! I was bewildered, because I hadn't realized that there's a private campground right across that little road. If you're after a little peace and quiet, book on the opposite side of the campground. 

Proximity to the main visitor center is a huge plus, as are the two nearby dump stations. It's not in a particularly beautiful part of the park, which is huge. You'll need a car to explore. We biked to a couple of trailheads, but the park's scale really does force you into car mode.
