Hike the Trails and Help the Park!

The goal of the Weed Free Trail 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 and waypoint creation
  • Outreach
  • Cultural site recognition
  • Park radio communication
  • Safe hiking principles
