    TRAIL SAFE! is a unique safety training program designed specifically for National Park Service (NPS) Trail Volunteers, but is useful to everyone! It’s based upon NPS Operational Leadership Training, where the human factor of safety is explored. TRAIL SAFE! captures (捕捉) the core learning objectives of the 16-hour Operational Leadership course while allowing volunteers to learn from their own homes online.

The TRAIL SAFE! series includes eight video lessons, each ranging in length from 18 to 40 minutes long. Watch them over the course of multiple days, or “binge watch” the entire series in three hours—it’s up to you—but please watch them in order from Lesson 1 through Lesson 8. After viewing the lessons, send your training verification (验证) emails to register your participation. When you have viewed and registered for all eight individual lessons, each participant will receive a TRAIL SAFE! pin and a SPE/GAR card in the mail for use in the field. Thank you for helping to make Sleeping Bear Dunes one of the safest work environments for NPS Trail Volunteers like yourself.
