Bring water and take a hike
This area is best for its hiking and photo ops, in my humble opinion. As with most desert campgrounds in Arizona, there is not much privacy between the sites but take advantage of the beauty. The waterfall trail is an easy hike and very doable with kids. You can only bring a stroller so far unless it's an off-roading stroller but the hike is worth it (especially if there's water flowing). There's a playground across from the trailhead in case all else fails and someone stays behind with he little ones. Restrooms are thoughtfully placed here. DO watch for rattle snakes on this trail and all for that matter. Also, bring a lot of water and then some. Stop at the Visitor Center and library on your way in. You're not far removed from civilization so anything you need is just a brief drive away.
