Like the Simitar-horned Oryx, the Addax roams freely within this national park.
My standards are admittedly fairly low for what qualifies as "wild" these days but it's pretty easy
to consider Bouhedma fully wild. While it is fenced around the edges, it's very large.
You can drive all day and not see the same area twice. Plus predator and prey coexist so... I say it's fully wild.
