The heart of the Arizona Climbing and Adventure School (ACAS) resides with its instructional staff. Every course bears the mark of its instructor's leadership and vision. ACAS instructors are dedicated educators, caring and skilled in a number of disciplines. Whether leading a technical ascent or explaining the nuances of desert ecology, these men and women form the backbone for every course.

Instructors are selected for their maturity, judgment, teaching experience and outdoor skills. A genuine interest in people and love for teaching are as important as an extensive climbing resume. Our select instructors are AMGA, PCGI, Leave No Trace (LNT), EMT and Wilderness First Responder certified. Many have worked at other outdoor educational organizations and schools such as Prescott College, the National Outdoor Leadership School (NOLS) or Outward Bound. Their years of climbing, canyoneering and teaching have made them unequalled in safety and experience. Climbing and wilderness adventures are more than our business, it's our way of life!

We at the Arizona Climbing and Adventure School (ACAS), want personally to tell you how pleased we are that you are considering joining us for a course. If you do come, you will look back on your ACAS course as one of the great adventures and learning experiences of your life.

Along with adventure will come challenges.
Indeed, the very purpose of ACAS is to help you find untapped resources within you; to let you discover that you have the ability to do more than you thought you could.

The number one concern our students have before coming is "not being able to meet the physical challenges of the course." We address that concern by encouraging a noncompetitive and nonevaluative learning environment. You set your own goals for the course. And you are the sole judge of your success. Upon completing the course, better that 95% of our students felt they benefited greatly from the experience.

Our Course's Focus On:

... Transcending self-imposed limitations
... Self-knowledge
... Tenacity
... Teamwork and responsibility
... Promote skill mastery
... Leadership skills
... Self-reliance

Each course has a set curriculum; depending on which course you enrolled in, expect to camp, hike, make challenging decisions, rock climb and rappel off vertical faces, explore deep desert slot canyons; but don't expect your course to happen in any routine way or on any particular schedule. The itinerary, the route, the staff and the weather will all work together to make your course unique and challenging.

Each course offers you the opportunity to risk, to trust, to try and to learn. Our courses and workshops are designed to allow you to learn by doing. You will be asked to be an active participant, to experience adventure based programming firsthand. You will find that our courses can leave a lasting impression on you.

Expect your course to be dramatic, exciting, educational and fun, but be prepared for it to be even more. Your ACAS experience is still ahead of you. The itinerary has yet to be finalized; you and the uncontrollable forces of nature are about to write the story.

Be ready for anything. Get personally invested. Get excited. Get ready for one of the truly great outdoor experiences of your life!

We hope you look forward to being with us as much as we look forward to having you!
