This park is temporarily closed to vehicular access, meaning there are no parking facilities and parking on roadways is prohibited to protect public health from the COVID-19 pandemic. Diablo Foothills is an imposing and inspiring gateway to the beautiful parklands of Mt Diablo State Park and Walnut Creek Open Space. The foothills’ 1,060 acres are valued for their interesting geologic formations, their sweeping panoramas of the San Francisco Bay Region and the rural quality of the adjacent rolling grasslands. This route starts out in a suburban neighborhood and follows a regional trail to take you quickly into rustic parklands. You will enjoy rolling hills of scattered oak woodland, beautiful rock outcrops, and a meandering, seasonal creek as you make your way around the loop. In Pine Canyon, keep your eyes open for peregrine falcons, as they are known to use the rocky cliffs for nest sites. Make sure to bring water and use the restroom before you take off for the hike; there are no amenities in the staging area. Dogs are not allowed on the trails in Diablo State Park. Park at the Livorna Staging Area, cross Livorna Road, and make the first right onto Serafix Road. Once on Serafix Road, take an immediate left through three fence posts to access the Alamo Trail. Follow Alamo Trail behind the housing development and uphill through a cattle gate. Continue uphill past the next trail marker, making your way past the water tank. At the next trail marker turn right onto Hanging Valley Trail. Continue until the next intersection where you will turn right onto the Briones-To-Mt. Diablo Regional Trail. Shortly, you will pass through the gate that divides EBRPD parklands and Mt. Diablo State Park. Stay on the trail as it goes over the rolling hills, passing the giant outcrops of rocks on your right. At the fork in the road stay to the right; at the next trail post, turn left onto Little Yosemite Trail. Follow Little Yosemite Trail as it winds along the hill and follows the seasonal creek. Cross the small wooden footbridge and continue straight; the trail will become Stage Road Trail. Follow Stage Road Trail to the left for about .75 miles and then turn left onto Fairly Lantern Trail which leads you to Buckeye Ravine Trail. Ascending the hill, Buckeye Ravine Trail will lead you steeply through the narrows of two hills. At the plateau, make a left at the next trail post onto Mokelumne Coast-To-Crest Trail. At the next immediate fork in the road stay to the left and stay on Mokelumne Coast-To-Crest Trail for .81 miles. Turn right at the next trail post onto Hanging Valley Trail for .34 miles. At the next trail post make a left, continuing downhill on Alamo Trail. Alamo Trail will take you all the way back to the Livorna Staging Area where you parked.

So, so muddy after the rain. But it was still incredibly beautiful and peaceful with the gray skies and the fog clinging to the tops of the hills.

Pretty uneven footing with the rain and subsequent dryer weather. Good rolling hills, but the overgrowth makes it difficult to spot all the pot holes.

Went 4/1 after a few rainy weeks and the trails were still pretty muddy and super rough from cow hoof prints. Made it pretty tough but still lots of fun. Be aware in rainy season that you have to cross the creek a few times and will probably get a little wet! It was half a foot deep when we went and did some rock hopping to get across. Saw lots of cows, deer, turkeys, and what was either a bobcat or small mountain lion (didn’t get close enough to find out!). Keep an eye out!

Wow! Great trail! I added on Foothills Trail to bring the hike in at 8.3 miles. Love all the rock formations, streams, woods and rolling hills! After more rain, should see a waterfall too! I didn’t feel that it was a hard trail, definitely moderate but not hard.

simple pastoral trail typical of the East Bay hills. nothing particularly impressive. the day was beautiful and clear skies made for a picturesque hike.

This should not be rated as hard. I've done moderate rated trails that were harder than this. Fire roads mostly, but once you get to Little Yosemite, then you have some single track. The huffer and puffer was Buckeye Ravine Trail - if you follow the written directions. That will get your heart pumping for sure. I saw some turkeys and deer very early on in my hike. You are in the sun for a lot of this trail, so plan accordingly. There were way too many bicycles and horses on this trail for my liking. I'd do it again when the hills are green, but only during the work week, not on a holiday or weekend. Between the cow and horse poop, all you do is keep your eyes glued to the trail to step over it. Perhaps that is why the trail is rated hard.
