rock climbing zionStephen Darveau is a Utah local who was born and raised in SLC, and is currently living in Virgin, UT. His parents were very active all the time and his mother was a professional aerial and mogul skier.  Stephen’s first guide gig was guiding snowmobile tours near Park City UT. As much as he loved it (saved his life after the death of his first son Gabriel) Stephen quickly realized that lifting those heavy machines out of the snow all day was a just temporary job. On the other hand, rock climbing and canyoning have been known to save his soul. Stephen has been climbing for over a decade and guiding rock climbing and canyons in Southern Utah for over six years; during that time, he has incorporated rock climbing and canyoneering into a few different residential treatment centers around town. The therapeutic value has had a great deal of influence on many lives including his own. It is Stephen’s hope to maybe share some of this experience with the guests of Rock Odysseys. He has two children, Lykan and Olive.
