Yosemite National Park advises visitors that the use of Unmanned Aircraft Systems (Drones) are prohibited within park boundaries due to regulations outlined in the Code of Federal Regulations (CFR). Specifically, the use of drones within the park boundaries is illegal under all circumstances. Thirty Six CFR 2.17(a)(3) states, “delivering or retrieving a person or object by parachute, helicopter, or other airborne means, except in emergencies involving public safety or serious property loss, or pursuant to the terms and conditions of a permit” is illegal. This applies to drones of all shapes and sizes.
The park has experienced an increase in visitors using drones within park boundaries over the last few years. Drones have been witnessed filming climbers ascending climbing routes, filming views above tree-tops, and filming aerial footage of the park. Drones can be extremely noisy, and can impact the natural soundscape. Drones can also impact the wilderness experience for other visitors creating an environment that is not conducive to wilderness travel. The use of drones also interferes with emergency rescue operations and can cause confusion and distraction for rescue personnel and other parties involved in the rescue operation. Additionally, drones can have negative impacts on wildlife nearby the area of use, especially sensitive nesting peregrine falcons on cliff walls.
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.
