• Making or changing campground reservations in National Parks; 
• Inquiring about trail conditions or backcountry safety in National Parks; 
• Reporting problem trail conditions or closures in National Parks; 
• Emergencies while hiking in a National Park; 
• Reporting wildlife sightings or incidents within National Parks. 

 All other questions about the GDT can be directed to the GDTA.
