This is an excerpt from a GRNC posting referring to the laws that take effect Dec 1. For now, and even after, check the local/county ordinances.
Section 21(b): Amends statewide firearms preemption such that local governments may still ban firearms "on local government buildings and their appurtenant premises," but may no longer ban firearms in parks. Due to the weakening amendment made by Rep. David Guice, a local government may still ban firearms in specifically named "recreational facilities" (defined as playgrounds, athletic fields, swimming pools, and athletic facilities), but gun owners may still keep firearms in enclosed compartments within motor vehicles.
This is from the NC Parks and Recreation site:
Are firearms allowed in a state park?
All deadly weapons, including firearms, airguns, bows and arrows, sling shots, or lethal missiles of any kind, or other deadly weapon is strictly prohibited in all areas owned or operated by the NC Division of Parks and Recreation except for commissioned park rangers and other authorized personnel. Cap pistols and fireworks are also prohibited
