Highlining & Slacklining

Highlining and slacklining are increasingly popular activities in Joshua Tree that involve balancing and walking along a length of webbing stretched between two anchor points. For safety, highliners should wear a climbing harness leashed to the main line. To protect park resources, and especially Joshua trees, please observe the following rules:

  • Slacklines may be attached to rocks, but not to vegetation. Joshua trees have shallow root systems and cannot handle the torque that a tight line requires.
  • Slacklines are not permitted in campgrounds because of safety concerns and damage to park resources. Improperly placed slacklines have broken picnic tables, toppled Joshua trees, and dislodged bulletin boards.
  • Unattended slacklines and fixed lines will be removed by rangers and the owner will be cited.
