This hike is off the beaten path and then off that beaten path. There are no maintained trails and you have to hop some fences. The view at the top is absolutely worth it. There are some tight holes you have to crawl through and some treacherous cliffs to navigate.

Invigorating and beautiful in the fall. We enjoyed the variety of ecosystems. North end of trail is rustic but this app keeps you on the right trail.

The best part of this trail is the rocks you can climb off trail. That is where the great views are....

Great hike. Moderate grade creeks and some great views when you get to the top. Only do the loop part if you are an experienced hiker and can bushwhack through the wilderness

A relatively easy hike until this loop at the southmost point. There is NO trail there. We persevered trying to make our way using GPS & finally did, but it was nothing less than treacherous and in my opinion DANGEROUS. This loop on this trip should NEVER have been left on the AllTrails site. We are very experienced hikers and never have encountered anything like this. Our worst hike ever (and we hike 72 miles/month)

More of a walk than a hike. Slight incline but mostly flat. Not much to see other than trees.

the end loop isnt marked, but other than that it was a variety of sights and types of trail, bolders, sands, gravel and rivers.

After reading the reviews, we headed straight out expecting no loop at the end. Sure enough, no readily visible loop. Tried following the GPS path for a bit also but turned back and just made it an out and back. Too many branches covering the path you were imagining more than seeing.

But for the path you could rely on it was great and covered overhead for most of the first half with paths that crisscrossed a small stream. Nice, cool and relaxing. The second half you got up high enough to see the rocks around you but not any long distance views. Most of the rocks you were seeing were actually those from the first half of the trip. Good spots to stop and rest around the rocks in the first half of the trip. There were plenty of Aspen and Birch trees along the route which would probably make it a good hike in the Fall as well.

Overall, a great hike for a cool June Day.

Nice easy trail. No loop though. We tried to find it but realized that it was purposefully covered with brush. Needs updating in this app.

Cool out and back trail with several views. It can get a little confusing so use the map on AllTrails. I attempted the loop at the end going counterclockwise. It is overgrown but easy until I got pass the half way point on the loop. It got harder then harder and even harder with deadwood and underbrush where I had to bail and cut back across. I do not recommend doing the loop.
