I think many people in Austin know this place!
There is a cliff wall that can be traversed up the side on an easy trail that overlooks the 360 bridge. It's always a beautiful place to come see the sunset over the Colorado. I walked up here a few nights ago when I had the feeling that a good sunset was coming (it's in my bones now). There's also this oddly-shaped tree up there all by its lonesome, and I felt like it should be included too.
