Parachuting (or BASE jumping), whether from an aircraft, structure, or natural feature, is generally prohibited by 36 CFR 2.17(a)(3). However, if determined through a park planning process to be an appropriate activity, it may be allowed pursuant to the terms and conditions of a permit.

This is not an appropriate public use activity within national park areas, and is prohibited by 36 CFR 2.17(3).
