Pretty easy hike, but as I discovered today, not very suitable for someone pushing a wheelchair. Easy walk tho if its just a walk. And there are horses to watch too.

Nice place for an easy stroll with the family.

The trails are awesome. I look forward to the season when you can go off the beaten path and go explore the large rocks. Currently it is closed sometime in February until the end of July. Once it opens up come August Im going to be all over this place.

I love the trails, free parking & theres a public pool. Its the perfect example of Californias beauty.

Beautiful spot. Great place to see wildlife, cows and horses! Ive seen rattlers and tarantulas out here, s get your camera ready! If you go far enough out, you will be alone with nature; even on the weekend.

It is a place to great hiking, however it’s little water than before.

A nice hiking area with some great views of Mt. Diablo, multiple trails, and some unique rock formations.

Good point to start a great hike !

This is one of my favorite places to hike my dog, as well as Briones. Its beautiful and well-managed.

It is so quiet and good place for trailers. Strongly recommended.when you need to be relaxed,then you listened the birdsong and saw cow climbed the top and half mountain .

Beautiful but because of Covid-19 some of the park is closed. We couldnt see the sand formations because the Perrigan Falcons are nesting. We are definitely going back.

My dad took me here when I was a kid, now Im bringing my kid here. Great place to relax, work out, and enjoy nature. Love this place.

We just come here to watch the horses in action but the trails are great

Really good hiking trails that are good for all ages. There are options to take more difficult routes, but the main trail is fairly easy. Some small hills & a couple really fun caves to explore. There is access to water & bathrooms at the entrance. Plus there is a pool & park near the main entrance, but I have not used either. Last time we went we found a really cool tarantula.

Great place to have birthday parties or other events. Ive been going there since l was a child. Beautiful setting and fun place. Bring your suit and a baseball stuff and you cant get bored. We always bring our own food to bar b que.

Best hike after work ever!

So many trails and hills feels like your out on your own

Very cool rock formations to see. However, all the trails except for the Stage Road are steep fire roads, some badly eroded. Even though I came during the middle of the day on a weekday the park was full of off leash dogs that were NOT under any semblance of voice control as required by Ordinance 38. I had to use my hiking pole to fend off the dogs.

This is such a peaceful and wonderful hike, with nice views of the mountains, there are some water crossings and lots of cows. I really enjoyed it and am planning to go back for a picnic as there are many tables and benches throughout the hike.

Nice place for an afternoon hike

Beautiful views, good workout, once you get to a certain point in the main trail, theres good shade. Really fun to hike and mountain bike. There are restrooms and picnic tables on the way in. Extra parking lot. We love it here!

Always an amazing place to hike/bike

Nice trails, can get hot someplaces

Different trials you can explore.

I never get tired if this hiking loop.

A great park, especially for large groups. Also smooth paved trails that people with wheelchairs can access

Great park! Nestled in the valley, right when the sun comes up, its really amazing. Great trails for running, and great scenery.

As usual we enjoyed our hick. Thank you for all your hard work!!

Great place to enjoy the outdoors so close to home

Love this place, been going here for all my life. Easy beginner hikes and more advanced, year around hiking

Great trails, clean bathrooms.Limited parking except for events

On the northern, lower slopes of Mt. Diablo, this secluded regional park is accessed by a two lane, in out road that is fully paved...but that was done long, long ago. there is parking for about 150-200, most of which is not shaded. there is an open picnic area adjacent to the trailhead, but if you hike or mountain bike, bring water, because the north and east slopes of Diablo are unforgiving. there is an equestrian center nearby which is a pleasant way to pass the time after a day in the hills. sorry, no pics. the trees make it tough to get a representative shot.

This place has so much to offer from hiking to swimming to mountain biking your van do it all even Rock climb. Castle rock also has an entry point to Mt Diablo

Absolutely beautiful here. A wonderful place to hike!

I have been blessed knowing Ron & Ruth Ford since the 60s. My Mom was a Life Guard there for years. We were there every day during the Summer months. Our family had ur Family Reunions there for several years. Excellent surroundings to stay the whole day. Big Oak Trees shading the grass area. The lawn area also had places to get a tan. Great clean changing rooms, showers, and the parks layout you always had a scenic backdrop. Baseball Field, Volleyball, hicking, dance floor area & Jukebox. I started working in the Snack Shack with Ruth Ford & loved it. I also flipped burgers, worked the major corporate private company Picnics.I too was a life guard there. I moved to the San Mateo County for 18 yesrs. I have driven to Castle Rock Park since I moved back to Concord. I will never forget the Fords, its the greatest place on earth I might drive up there next week. the memories

Such a beautiful park. Plenty of picnic areas and great trails. Parking can be a bit limited close to the gate though.

Great place for events but needs more maintenance

Good selection of trails for varying fitness levels.

This park is so beautiful and filled with various amenities; picnic table, grills, huge field, trails, pool, basketball courts. Its great! We go there at least twice a month and its never crowded. If you need a walk in nature or just a place to relax come here.

For climbing this is a very rich area. BUT, it is a mile mildly uphill hike to get to the turn out for the pine canyon/castle rock. Then its across a creek and up steep unmarked canyons. The trails are not marked after the turn up hill. Mountain project is a great resource but it will require a full morning of strenuous recon before the pay off. The payoff are amazing views and flakey sandstone cliffs. The creek is nice to hike along in winter but dry in summer. Overall, excellent for adventuring but not for a casual day climb.

Awesome place for hikes and views!

Nice place for a hike or bike ride. Decent size trails. Parking can be pretty difficult as there arent many spaces but they also have a lower lot to park in.

Love this place, best hiking in Northern California!

I use to work there in the mid. 70s best time of my life ... for Mr. And Mrs Ford...bless their hearts thanks for the memories

Friendly and passionate rangers make this a safe and beautiful park

Great hike! We do it at least, twice a week!

Nice day hiking on the side of Mt. Diablo.
