Spadra is a pretty spot on Lake Dardanelle
Spadra Campground is run by the Corps of Engineers so as expected it is pretty well maintained. The showers and bathrooms are clean. The campsites have plenty of space between them with plenty of pretty lake views from most of the sites.
The only thing you should be worried about if you have small children is the railroad tracks near the campground. There is an access road that separates the sites from the tracks, but keep a close eye on your children if they are the kind who like to suddenly run off or disappear while exploring.
This is a great campground if you have a boat. There is a boat ramp with access to the lake and nice places to rest on shore.
