I stayed at a hotel within walking distance and went to check it out before I left. I'm glad I did! It was quiet, beautiful, and the views were endless on a clear day. The dam is a marvel and the tall canyon walls were something to admire, however, I enjoyed the sandstones along the path the most. There are a few parking spots there but in February it was empty and a great time to view.
Note: there isn't anything here, just a parking area and a trail with some overlooks for free.
