Information for Leaders

scheduling

  • If you are scheduling this as a non-course related activity, please limit your group size to the recommended party size. The maximum party size is for use by course field trips only, and includes both students and instructors. Group size maximums do not reflect how course field trips are run (in smaller groups of students and instructors), but allow for course leaders to register the course in our system.
  • If you are scheduling a course field trip with more than 50 total people (including both participants and leaders/instructors), please contact staff at info@mountaineers.org so we can reach out to State Parks staff to notify them (at least a few weeks ahead of your field trip).

permits

  • The Mountaineers has a commercial use permit with Washington State Parks for all free and fee-based outings at state parks. Leaders should carry a print or digital copy of our  commercial use permit to show rangers they may encounter.
