Grand Canyon and Colorado Plateau conservation advocates : Grand Canyon Trust

Home » Grand Canyon » Natural Quiet » Issues


Airplanes and helicopters continue to erode the visitor experience in Grand Canyon — despite key legislation.

Since its inception in 1985, Grand Canyon Trust has worked to protect the solitude and stunning quiet in Grand Canyon National Park. Nevertheless, over time, a growing number of air tours has eroded the park’s serenity and replaced it with the sounds of throbbing helicopter rotors and airplane engines.

We were instrumental in securing passage of the 1987 National Parks Overflights Act, which sought to curb the expanding air tour industry.

Yet, after more than two decades, final rules have yet to be adopted for implementing the act.
