Beautiful trails, moderate elevation gain. May not be great for summer hike as most places are open without any shade. It would perfect for winter hike.

This place was very cool.This is such a beautiful place to visit especially for Photographers. Highly recommended but not was the best tourist spot for me.

Best off leash dog park in the East Bay. Located at the end of Casle Rock Road. Been working with my Search and Rescue K9s for 25 years and just a nice leisurely hike with some real grinders thrown in. Especially fun in the winter when the streams are running fairly strong and deep. My dogs love it.

Its a rather short hike up to the bench at the peak, and is beautiful.

Beautiful scenery with creeks, trees, wildlife, and hills to climb. Some parts are hilly but other than that, its an easy going hike. Definitely bring water regardless if youre going in the morning or mid-day. Enjoy your Hike!

Amazing hills and views. Need a middrive ebike for sure.

Awesome shaded hiking area. Steep hills if you wish or you can walk at the base of the hill for a much easier hike.

Im on the Peregrine Protection Team in the Diablo Foothills and its like being a tiny person in a beautiful vast place where you feel connected to nature. Its great for hiking, not a lot of steep trails and its got streams to cross over, picnic areas, lawn and the views are spectacular! The Pine Canyon cliffs are closed to the public during Peregrine breeding season, Feb 1 - July 31 (tresspassers ARE fined, just be aware). The rest is open for your pleasure though.

A nice regional park with multiple trails and views. Most trails are fire roads and multi use but are decent.

In early January it’s nice green after some rains. View is beautiful and the hike is easy and enjoyable .

A beautiful escape. Many trails to choose from depending on the difficulty you prefer and your activity. Some lovely natural rock formations as well.

What a great hike through the trees. Lots to see a you can make this hike to your level of fitness. Safe and lots of friendly people along the trails.

Nice mountain bike loops possible, convenient parking.

What a great place to go for a walk.

Wonderful hiking trails that are off-leash dog friendly!

Love this park. Everyone abided by social distancing and they would pull up their masks if we walked by them.

Great place for spring flowers. It’s usually not fields of flowers but good one offs. Area popular with horse riders so trails have associated horse “deposits” and horse vs dog confrontations seem frequent.

Its a very nice place to hike with beautiful views.

Beautiful make sure you have reasonable hiking shoes and time.

Beautiful area! Thank you for being open.

Fun times great for hiking, biking, horses, and picnics.

Gorgeous Nature a Wonderful Park.

Great view and nicely maintained.

Great place for a hike with the pup

Dont forget a big bottle of water in a camera to make sure you take your pictures and be sure to check the weather. I can get really hot and uncomfortable, but if you pick a cool day this is a really nice place to enjoy some Outdoor Adventure. Take a couple of friends and enjoy many different levels of activity and good conversation with people you care about.

Beautiful hiking close to downtown. Leash optional in most areas!

Me and my pup had so much fun on this trail. Because its a free roam, they were able to explore! Cant wait to go back again.

So much variety all close to home - a hiking favorite

Theres nothing better than a fun hike with your two obedient German Shepherds. This is a great place to hike.

Nice park with lots of wilderness

How can you not enjoy this varied place with hiking, biking, and much more. If you are outdoors in nature you will love the variety of activities that you can enjoy.

So beautiful! We love it

Beautiful views and paths to walk if youre looking for something really hilly to challenge yourself and some flatter ones if you want something easier.

Beautiful picnic area, with pool. Small hike in from p parking lot. Staff very friendly

Great place for a good hike. Dog and Horse friendly

Great hiking location!

Nice and crispy weather hike with dog friendly park.

The drive up to the summit is both beautiful and a reminder in safe driving. Many bikers were injured by unaware motorists so signs were installed extolling better awareness. Once at the summit the scenery is impressive. There are numerous trails but only a few are accessible from the summit so plan your hiking before you drive up. Trail maps are $6 and the bathrooms have a unique aroma . Lots of trails to hike and lots of cool history to learn about.

Its a nice place located just a few miles from the busy east Bay. Plenty of parking and lots of trail. Just adjacent to the Castle Rock Park

Its absolutely beautiful here! I hiked here during the end of August. It wasnt overly busy (during a weekday) but I did see quite a few other hikers and bikers. Theres so many different kinds of plants, and I even saw some lizards (and of course birds). The best time would probably be mid-September as the blackberry bushes should be fully ripe by then.

Sheer beauty everywhere!

Free parking, good trails, some steep.

Nice pleace

Nice hike today.

This place is amazing. Allows off leash dogs, and you can really get lost out there. My favorite time to go is in the winter when the hills are green. Beware of going right after rain, though. It can get muddy.

Beautiful veiw

More proof of American Socialism in these free to use absolutely beautiful public lands. When will the oppression end. Thanks Obama!

Beautiful place to go. Parking wasnt fun though.

Beautiful no open bathroom

Amazing views from the top. Great for road and mountain biking.

View is beautiful and the hike is easy and enjoyable .

Great place to spend the day hiking.

Great place for a weekend with the family! Nothing too gnarly, but plenty of hills!

Good place to run trails and get some elevation.

Phenomenal place to hike. Beautiful sights & animals from Turkey vultures to geckos. I would give it a 4 but I bumped it down to a 3 due to the fact that the Death Cap Mushroom (which has a 90% fatality rate) grows here. So hike at your own risk & with extreme caution. Stay away from any & all mushrooms you see here.

Any season to visit this place for hiking is always a change of scenery, can never get tired of it

Beautiful place, but if you bring your dog keep he or she away from tall grass because they might get ticks. Theyre easy to remove though.

Nice variety of trails, so close to home.

Great trails and an expansive park. Spent my first visit at the west end on routes leading to Castle Rock. Did not disappoint! The rock formations are amazing and the views beautiful along the way. It features diverse landscape scenes despite the dryer season (hay-like grass everywhere).Take a picture of the maps at the ranch entrances. This is a must! Google Maps doesnt offer much help for navigating within. The local maps are accurate and will keep you sane. This park is huge and has plenty to return to. Excited for the next route!

Lots of parking, few crowds, nice trails

Lovely easy hike in the hills. Castle Rocks is beautiful.

Always amazing

Great spot for the family. They have basketball courts, baseball field to play on and a swimming pool. Nice place for a hike too. Lots of trees

Nice area and great day hike

Free destination including parking. Its a nice change of pace from everything surrounding it. My dog really enjoyed staring at the cattle.

Its raining...so no Tarantulas out today! : )

A lot of hiking and biking options. Fire roads as well as single track.

Beautiful hiking trails

Good for walk

Beautiful place.

Good place for a quick hike or bike ride

It is lovely place to walk around, unfortunately this place is Ben close some areas because some idiots dont know how to respect Parks and the ones who respect and care dont get to enjoy some areas .

Nice hiking! When I was there, the rock area was closed for nesting raptors, but even still, the paths are good, and the trails are kept up.

Fantastic running, hiking and mountain biking trails with plenty of elevation gain and loss for a great workout. Connects to other agency trails.

A lot of shaded areas nice and moderate hiking trails. The pool is a nice extra the the little ones will enjoy.

Such a nice off leash dog spot

Few places prettier around these parts while its green in early spring, but it can get muddy. Still awesome the rest of the year.

Lots of nice trails to roam around on for all levels of hikers.

Great place for a day hike with views of Mt. Diablo, Walnut Creek, and Alamo. Rolling foothills with wide and narrow trails and creeks crossings. Connects to Mt. Diablo State Park and has cliff area where peregrine falcons nest.

I spotted a snake on a trail. Please be careful

Coco SAR training grounds

Beautiful! Just watch out for snakes.

Beautiful and expansive views, peacefully serene, with old oak trees sprinkled throughout the landscape, offering shade to passersby

Dont climb in Pine Cayon after it rains - saw some folks break some holds off there after a few days of rain. This placell get ruined if people continue to do so

Great place to enjoy the out doors!

Beautiful Place, Pick up your dogs excrement.

Yikes

Great hiking

Lots of different trails and great shade when its hot in summer.

Nice wide trail. Some water to be a bit wary of but overall looking lovely this year.

Just Beautiful

Awesome views

Good place for hiking and picnic. Has a swimming pool

I entered the park from the Livorna Staging Area (which I had to myself!) January 30th, 2016. The trail starts off nice and flat alongside a gated neighborhood, then forks through a small boggy area. If you fork right you end up in the neighborhood on Serafix Rd. Its a short distance, so when you realize youre going the wrong way you can come right back to the trail and fork left to continue! Once I started uphill it became a little muddier with a small washout area down the center of the trail, but a good pair of hiking shoes aided in the climb.Unfortunately, I didnt realize how much of a challenge it would be to get back down the now steep, muddy hill. I made it up to the cattle gate, where the land seems to level off and dry out but could not find stable enough footing to open the gate and walk through.I absolutely want to come back here and finish the hike I barely started, but strongly advise waiting until the ground is more firm and less muddy.

Hidden gem close to home!

Love this place for hikes and even has a swimming pool

Nice place

Excellent views of Mount Diablo and the Bay

Great place

So many trails and beautiful scenery
