This is my experience applying for filming permits to record video in National Parks and post the content on YouTube. The First Amendment to the Constitution guaranteeing freedom of speech and freedom of the press should protect us from unreasonable permit and fee requirements when visiting public lands.

Detailed Description of Onsite Activities (from my permit application):
A single vehicle will use regular park roads and parking lots. Filming locations will be limited to marked trails and other outdoor spaces which are specifically shown on National Park Service maps obtained at the park Visitors Center, and will be selected on the day of arrival based on favorable weather and trail conditions. Locations will be accessed by a single photographer on foot carrying only a daypack, including one iPhone, one GoPro, and a compact tripod. None of the photographer’s vehicle, equipment, or clothing will include any advertising or marketing, and the photographer’s activity in the park will be indistinguishable from an ordinary park visitor. Filmed footage will consist of park scenery and the photographer speaking to the camera. The purpose of the project is for posting a brief video of personal travels on social media, such as YouTube. The requested use is an exercise of a First Amendment right, and therefore no fee is included.

National Park Service Response (all 7 parks had the same response):
Dear __________,
We have received your application for a Special Use Permit for Commercial Filming/Still Photography at _________ National Park. Based upon the description of the activities provided in your permit application, it does not appear that they would constitute commercial filming under federal law. As a result, you are not required to obtain a special use permit for commercial filming or pay associated fees. You are responsible for securing any necessary permissions or releases if you will be filming other people in the park. In addition, all filmers must comply with regulations that apply in the park, just like other visitors.  Thank you for your interest in visiting _________ National Park. We hope you enjoy your time in the park.
