We started at 5am. I wouldn’t start any later in the summer because it’s exposed. It was a nice wide trail. Well marked. Wish the loop continued in the foothills and didn’t hit the street at the end but regardless it was a well marked, well maintained, and well traveled trail. Boise State has a bird research area at the top and we enjoyed learning about their program and releasing birds after they were banded. It was a great hike. Bring lots of water. Start early.
