"We have serious concerns about the negative impact that flying unmanned aircraft is having in parks. We are prohibiting their use until we can determine the most appropriate policy that will protect park resources and provide all visitors with a rich experience," Jonathan Jarvis, director of the National Park Service (NPS), said in a statement.
The NPS is the US government agency that manages the nation's national parks, monuments and other historical sites.
According to officials, the drone ban will cut down on the number of noise and nuisance complaints filed by visitors, and will help ensure the safety of those on NPS grounds.
"Despite the prohibition, the NPS may use drones for search-and-rescue operations, fire safety and scientific study," Jarvis said.
The ban, however, is a temporary measure until the government can assess how people can safely operate drones over densely populated areas, media reports said.
