Yes, we went there already. But it is so beautiful and such a nice simple and short hike, that we decided to take Austin there. Here's a photo of it from that day.
The deceptive thing about some of these places, Horseshoe Bend in particular, is that the photos you see, including mine, make it seem like they are private and peaceful settings. In reality, Horseshoe Bend is ALWAYS crowded. But to get your photo you go to the edge of the cliff and take it, so the people are behind you and to your sides and not in your photo. But it is always packed. So it's quite deceptive to look at photos of it!
