Crazy Creek Campground is a nice wooded campground near the North East entrance to Yellowstone National Park.  Crazy Creek is also the last developed campground as you head to the park that allows for tent camping,  from here to the entrance the campgrounds allow only hard sided camping units due to bear activity. 

Crazy Creek campground is a 16 unit campground.  Each site has plenty of trees which was great as it allowed my to use my hammock.  Each site has a picnic table and metal fire ring and plenty of room for your tent.  Campground has a vault toilet.  No water is available.  Campground is not ADA accessible.  Bear storage lockers are available as food must be stored in your car or one of the lockers.  Dumpster is available for your trash.  Sites are just $10 a night, but they fill up fast.  A great feature of this campground is the Crazy Creek trail.  A trail from the campground takes you across the highway to the trail,  a very short hike brings you to Crazy Creek falls.
