You generally do not need a permit for your personal, noncommercial filming and photography activities within normal visitation areas and hours. However, filming outside normal visitation hours and all commercial filming will require a special permit.
Commercial filming means filming that involves digital or film recording by a person, business, or other entity for a market audience. This includes recordings such as those used for a documentary, television or feature film advertisement, or similar project.
Commercial media coverage of breaking news never requires a permit, but is subject to the restrictions and conditions necessary to protect park resources from unacceptable impacts.
Still Photography (whether commercial or noncommercial), in accordance with Public Law 106-206, will not require a permit unless it takes place at a location(s) where or when members of the public are generally not allowed, or it uses model(s) or prop(s) that are not a part of the location's natural or cultural resources or administrative facilities, or the National Park Service would need to provide management and oversight to prevent unacceptable impacts.
