Edward, I am so glad to hear you and your son Gian had a great time on the Ephedras Grotto canyoneering trip! It is one of my personal favorites as well for all of the reasons you listed. However, I think the most important thing is that you and your son were able to share in an incredible experience that built up your relationship. That is exactly why we do what we do. We strive to craft an unforgettable experience that builds relationships. We hope to have you back to Moab soon, and wish you and Gian all the best in the many more adventures you will have together! Best Regards, Cort Wright Moab Adventure Center
