Hike the Trails and Help the Park!

The goal of the Weed Free Trails program is to hike Saguaro National Park's trail network while eradicating non-native, invasive plants that threaten the native ecosystem. Volunteer Weed Free Trail monitors will hike and examine trail segments a minimum of three times per year, independently and on a very flexible schedule.

Weed Free Trails is a great way to get involved with Saguaro NP and learn a variety of skills such as:

  • Plant identification
  • GPS navigation
  • Outreach
  • Cultural site recognition
  • Park radio communication
  • Safe hiking principles

Orientations are held periodically. Please email SAGU_Invasive@nps.gov or call (520)733-5179 with any questions regarding Saguaro National Park's Weed Free Trails Program.
