What is Jombok Hoas?

“Jombok Hoas” refers to the trees found in abundance at our Adventure Learning Center—and the ability to fly.

And yes, people really can fly if they believe in themselves and have experiences that collectively encourage them in whatever they wish to do.

Jombok Hoas is about creating experiences and showing people that with a little belief in themselves and in what they, together with their friends and community can do, then they can really do anything … and be anything that they want. Principles learned here can be actively applied in our lives for the betterment of ourselves, our families and our communities.
Jombok Hoas is a non-profit facility operated by the Adventist Development and Relief Agency in Cambodia. 

Adventure Objectives

Situated in the dense forests of Preah Vihear, Jombok Hoas was created to give Cambodians an opportunity for increasing various life skills through Adventure learning.  Jombok Hoas has developed programs for groups that work towards the following objectives:

Building Trust
Thinking Creatively
Finding Solutions
Helping Others
Empowering Individuals
Developing Team Support
Increasing Self-Confidence
Active Communication

Jombok Hoas’ programs have been designed to create positive and lasting change in your workplace, organization or team.  Programs focus on identifying and nurturing leadership and team building skills in addition to personal growth and self-confidence.  A variety of physical activities, and personal and group initiative exercises stimulate active communication, problem solving skills. These challenge individuals and teams beyond their perceived boundaries enabling them to realize great achievements… while some activities are just plain fun! 

An important factor for learning is the post-activity reflection time, conducted by experienced Khmer facilitators.  Each debrief-time enables participants to share what they have learned and how they can apply this skill in their lives.  It allows conflict to occur in a non-threatening environment enabling participants to constructively learn approaches to deal with it, as well as turning it around for the good.  Physical challenges are also used as representing life’s challenges and showing that a positive attitude and group support can be the difference between success and failure. 


Participants are able to experience a variety of high and low activities, all situated in the forest environment of Jombok Hoas, including repelling, high wire walking, zip line, giant swing, a cable bridge, giant spider web and others.
