Trekkers offers a 10-month program that culminates in a 12-day expedition for 10th graders during the summer. The focus of the expedition is to visit, explore and study the environmental uniqueness of a particular bio-region within the United States. Examples from the past include: the Grand Canyon, Mesa Verde National Park (Cliff Dwellings), Florida Everglades, Northwest rainforests, Mount St. Helens, Redwood National Forest and many more. Along with the life changing opportunities students receive from this expedition, they are also required to take part in a pre-trip life skills/leadership course. The course is designed to help students gain knowledge and confidence in presenting themselves professionally to others.
