Used to Hike this area as a kid before the area was all built up. I lived on Comistas and all the land behind us was cattle farming.
Wonderful trail with lots of streams running through. Be prepared to cross multiple creeks that cut across the trail. Most streams had rocks you could easily jump on to cross. There is a section of the trail that allows dogs off leash.
Due to the rain we had, a lot of the smaller trails that start from the main trail are closed. However, it is so green! The greenest I've ever seen! And the creek that the trail runs along is moving and noisy!
Very muddy, cattle tracks left very big holes down the entire trail.
This is a great hike but you need to do it when it is completely dry. The trail crosses what is usually a creek but is completely flooded and requires getting wet to pass if it's been raining. We had to turn back and go through Buckeye Ravine. About 75% of the trail was mud even after 4 days of no rain. The views are great. There are really only two areas of steep incline but besides those, it's an easy hike.
Great view. Didn't go till end. Walked less than 2 miles. We carried a stroller for our 1 year daughter and bike for our 6 year old. Some parts on the trail and rocky and steering the stroller is tough.
I parked at the trailhead and followed Stage Road, then onto the Little Yosemite Valley Trail. There was a steep climb. I turned right onto the Briones to Mt. Diablo Regional Trail. Followed the Mokelumne Coast to the Crest Trail, then hiked another steep climb onto the Shell Ridge Trail and went down to the Diablo Scenic Trail. The Diablo Scenic trail led me back to the parking lot. Total 6.3 miles with average 3.0 mph. I got a good workout.
Nice run. Semi-shaded through the Stage road part. Bringing water is essential.
Good hike, not much shade so bring a lot of water in the Summer. Good climb in the beginning and the end, great to run in the middle.
