Yes, but the skywalk is 4000 ft above the Colorado River, or the base of the canyon. It is not much higher than the average terrain. Still scary when you look down!
Good idea except you can't carry anything out there, not even a camera or phone, and you have to wear 'crime scene' booties. Better to do that somewhere else on the rim.
I think the highest observation deck in North America (U.S.) is probably on Pikes Peak CO +14,000 new visitor deck or Mt Evans
From one of the new decks looking south from the new summit house on Pikes Peak while under construction. I was working on the antenna placements and R56 work that was being done. The porta potties needed to be secured due to wind... June of '21, almost done. It's done and open now - cool place to visit!
