information for leaders

Courses, paid clinics, staff-led programs, and course field trips require a Commercial Use Authorization. The Park typically accepts applications for 2-year CUAs  through mid-March each year, and CUA's are activity-specific. Please contact info@mountaineers.org if you would like to apply for a CUA for a field trip or paid clinic for an activity we do not already have a CUA for. Please follow all Mountaineers group guidelines when leading trips or courses in North Cascades National Park. 

Notes:

• Leaders are responsible for securing backcountry permits or other required permits even if  we have a CUA.
• Leaders must have all relevant CUAs with them in paper or electronic copy to show Parks Staff as requested. 
• All Hiking course field trips or paid clinics must have a First aid and CPR certified leader. Current (non-expired) certificates must be uploaded to the park web portal by Mountaineers staff prior to the trip
• All mountaineering field trips or paid clinics must have a WFR-certified leader and a leader with documented climbing certifications (an AMGA certification OR Mountaineers climb leader with a recent resume of training and experience). Both qualifications must be uploaded to the park web portal by Mountaineers staff prior to the trip
