No drones in Yellowstone National Park.This means that area visitors are prohibited from using drones once they enter the park gate. The U.S. Forest Service prohibits drone use in wilderness areas, but allows drone use on general forest lands.
You can not fly with any UAS in a national park unless you got your P.107/Drone Pilot license, a permit and a waiver from the FAA. Other than that, without the waiver and permit you can NOT fly in a national park at all.
Visitors traveling to the park should be aware that the use of drones is prohibited while visiting the park and should not be utilized at any time. For more information about regulations about visiting Yosemite National Park, please visit www.nps.gov/yose.
If you fly a drone in an NPS-administered park, you risk interfering with the flora and fauna of the location. You can also disturb park visitors, hikers, bikers, camping tourists, etc. Drone pilots caught breaking the rules will be fined $5,000 and risk up to six months in jail.
