In addition, slacklining in Arches National Park is prohibited. Slacklining is defined as walking on a rope or other line that is anchored between rock formations, trees, or any other natural features. Height of the rope above the ground is immaterial.
These closures are based upon a determination that such action is necessary for the maintenance of public health and safety, protection of environmental or scenic values, protection of natural resources and avoidance of conflict among visitor use activities.
