Raven Rock State Park was created in 1969.
Raven Rock State Park is located at 3009 Raven Rock Road in Lillington, North Carolina. It is about a 45 minute drive from Fayetteville.
There is a hollowed out rock near megaton.
It is right next to the Broadcast Tower KB5 and near the Dickerson Tabernacle Chapel. If you head NW from paradise falls you will come to it. It is also SE of Raven Rock. It is also in the same vicinity of Mount Mabel Campground (Deathclaw Sanc is North of it.)
