Liked the short hike very much, especially visiting the Eugene O'Neill National Monument, that was special and made this short hike. But you can continue further on two trails, which we did do, to make the hike longer.

Extremely muddy!

Lots of mud after all of the rain! Wear shoes with good traction, I fell once when turning around on a relatively steep incline. Other than becoming very muddy, all was well from then on. Eugene O'Neill house was awesome! I returned via the streets due to the mud on the trail. Will do again, beautiful views!

Great everyday hike, several trails turn off from here so you can vary the length of your hike. Dog friendly on leash. It was muddy due to recent weather, but we did fine with good hiking boots. Beautiful views, only saw one other group. Some steep hills in places. Would definitely do it again.

Nice view of Diablo all the way. I took a longer rout, which took me almost 3 hours.

I agree this trail is not for beginners it's moderate to the steep incline is steady at least the .83 mile of it I got through. Definitely worth if you love views and a nice combo of shade and sun. It's not a maintained trail so returning can be challenging. I'm looking forward to getting to the summit will be going back.

Actually for my opinion this trail is more than moderate because when you go up, the slopes are long and very steep. It is a very good trail with view of Mount Diablo, as well as many tiny wild flowers thanks to this spring's rain. I took quite a few photos.
