Not possible to access trail. We drove according to the gps directions and encountered a padlocked gate indicating private property. ☹️

Not so good with a dirt bike. Narrow rocky trail makes it tough to ride. Great for a hike though. Very nice area

Great views of forest to start, after a decent downhill walk, it takes you to some more open areas. This is starting from the Highway 78 side to the North. Even a relaxing night hike if you don't mind using moonlight.

Beautiful, nature at it should be. No people in the trail.

Did the north side of the trail. Pretty steep incline coming back up but well worth it. Beautiful hike.

From the gate on Robb Road, it is a 3.2 mile hike one way to the trailhead according to my GPS. The road was still closed as of 4/7/16, but even when open, it is definitely only passable by jeeps and ATVs in its current condition. Pretty trail, but unless the forest road is open and you have a jeep, be ready for the 6.4 mile round trip approach.

Hiked this with my daughter and son-in-law in October. We chose to follow the river and not the "trail'. Awesome hike with many river crossings and some bushwhacking. Because of just a tight group of hikers and laughter one of the best hikes ever. Because of the bushwhacking, it probably seemed a longer hike, but would do it again in a heartbeat. The arch at the end is awesome. The high canyon walls, moss, fungi, and just total canyon experience of a rarely traveled trail is worth a weekend. And an awesome memory for the future...
