great trail I've only gone 3.2 miles of the the full 5 or 6 to the top. mainly because of time. I jog down every time. I'm going to get to the top sooner or later. but definitely not hard. be cautious of snakes, and at night coyotes. very recommended.
-- The trail is not as hard as described. The first portion is very easy, only when you get deeper into the canyon it is a bit harder.
The trail itself extends much further that the map shows, and this is the more interesting part, and a little bit harder. At the end of the trail you get to the a very steep canyon where the "mouth" of the river is, and this part is dangerous to climb. Many puddles and a very weak stream of water.
All in all a great trail.
I'm not sure would I would call this a beast. It's definitely a consistent climb that keeps your heart rate up and the elevation gain is significant. It was a nice way to spend the afternoon, but I'm not sure I have it on my list to do again.
