In its 14th season, the Grand Canyon Field Institute (GCFI) offers visitors the opportunity to explore one of North America's premier destinations in the company of seasoned guides. A program of the Grand Canyon Association, GCFI is dedicated to enhancing understanding and appreciation of Grand Canyon through firsthand experience. Utilizing the world-famous canyon as the "ultimate classroom," the institute's expert instructors share the rich human and natural history found above and below the rim. More than 90 classes are offered, including geology, photography, American Indian culture, desert wildflowers and backcountry medicine. 

GCFI outings typically require some level of backpacking. A few notable exceptions employ llamas, mules, vans and oar-powered rafts to carry the load. Classes that involve backpacking vary in length and difficulty and are designed to appeal to hikers ranging from first-timers to savvy canyoneers. GCFI conducts custom outings for groups and families whenever possible. Classes run year-round and are limited in size; fees vary. 

GCFI also offers "packaged" courses that include lodging, meals and transportation provided by Xanterra.
