This "trail" is so overgrown and poorly marked that you spend more time trying to find it than actually having fun. It is practically a miracle if you can make it through the chest-high thistle in some areas. Not worth the effort

The trail has all but disappeared after about mile 3. We navigated our way to the top, and found cairns every once and a while, but it required us making our own route that roughly followed where the trail should have been. We went back down Greyrock trail, and then took the road back to our car. It was a lot of fun, but if you want to be on a trail the whole time, this is not one to do.

$7 parking. I'm sure this is a lovely trail, but it is NOT for novice hikers like us. It wasn't physically challenging, but it was very hard to keep track of the trail despite occasional cairns. We got lost and went off the trail about 6 times before we just gave up, ended up going about 7 miles round trip. There was a burn in 2012 so there are tons of fallen, burned trees all over the place including the trial which made it confusing. At one point we even ended up having to cross over barbed wire, so we definitely weren't on the right track despite using the All Trails trail map. Wish we had just done the Greyrock Trail and actually made it to the summit. Again user error here, I'm sure more experienced hikers could have easily found their way but if you aren't great at navigation this is not the trail for you
