Followed exact course and GPS said 1,300 ft elev. Also 6 miles. It was beautiful!! Mostly runnable hills except for a few sections. Deer, rabbits, vultures. Some sections torn up by rain and then livestock. Made it more technical than it used to be. If running, highly recommend trail shoes.

Lovely hike through Caste Rock today. It's been breezy and temperatures in the high 60s, low 70s. I saw a family of quail, with lots of little ones still, and a family of turkeys with about 6 youngsters. Water running in the creek still and wildflowers still out but reaching the end.

Hard, not moderate. The last part has an extremely sharp downgrade.

This trail is mostly dog friendly, even with lots of off leash areas, but we did have to turn around and do a different loop as the end part is in Mt Diablo State Park where dogs aren't allowed

Some of the trails going outside the Castle Rock Recreational Area do not allow dogs, choose your loops wisely. Otherwise, great trails. Stage Road Trail has several small creeks to cross and good shade. Diablo Scenic Trail has amazing views, as well as Shell Ridge Trail and others.

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!
