Colorado mom Sue Hessler commented on her visit with a 3½-year-old, “We went to Black Canyon of the Gunnison, and boy, was that nerve-wracking!
"All those drop-offs. Brian isn’t a wild kid, but he’s not old enough to know the consequences of running up to the edge. It was pretty there, but I had to watch him so closely.”
It is hard to appreciate the view when you have to be hyper-vigilant of your children. But at Black Canyon, you have to be hyper-vigilant of your children.
Also, the canyon walls are a Mecca for technical rock climbers. Several climbing routes snake up the walls right below viewpoints. Folks may be roped up and climbing a hundred feet below you, and because the walls are so steep, and even overhanging in some spots, you might not even know the climbers are there.
If you kick or roll rocks over the edge or throw rocks (even tiny ones) down into the canyon, you risk hitting a climber or his partner on belay, endangering their lives. Signs are everywhere, admonishing you not to throw rocks, and the Park Service Law Enforcement is very serious about enforcing the rule.
As tempting as it is for them, DO NOT ALLOW YOUR CHILDREN TO THROW ROCKS INTO THE CANYON.
