Skywalk at the West Rim of the Grand Canyon. It's suspended feet above the Colorado River allowing one to have a 720 degree view, through the glass floor, of the Canyon!---The Grand Canyon is on my Bucket list.
I may have to take my massage license and move to Bali! A massage hut in Bali overlooking the crystal waters, clear glass floor to watch the fish while getting a massage. Now this is serious relaxation.
