Overview:
Raven Rock State Park is off of Hwy 421 between Sanford and Lillington, NC. The park is best known for its namesake rock - Raven Rock. The Campbell Creek/Lanier Falls Trails are about 5 1/2 miles when combined and can be completed in 2-4 hours.
Generally speaking, these trails are much less traveled than the the Raven Rock trail. Even on days when the Raven Rock trail is busy, these trails are usually deserted.
The visitor center has maps, restrooms, water, and a small museum. The visitor center is Gold LEED certified and there is a small display which explains some of the steps taken to achieve the certification.
Tips:
Swimming is possible at Lanier Falls in the summer but water shoes are highly recommended and you should be very careful on the rocks and in the water. If the river is running high or you are not a confident swimmer, you should probably stay out of the water.
Bug spray is recommended in the summer.
Dogs are allowed, but MUST be kept on a leash at all times.
