Rancho San Antonio County Park is a popular park in the South Bay Area that offers 29 miles of hiking, trail running, cycling, and equestrian trails that connect to the nearby San Antonio Ranch Open Space Preserve. Several challenging trails through this park lead to Black Mountain, whose summit is located in adjacent Monte Bello Open Space Preserve. The trail system goes through a variety of diverse environments including valleys, creeks, and ridges. The park is best suited for hiking and trail running. The PG&E Trail is a popular trail for runners. This trail stretches along rolling hills and electricity towers and provides a good cardio workout. Other popular trails include Wildcat Canyon Loop, Coyote Trail, Deer Hollow Farm Trail, which is great for kids, and the various trails that lead to Black Mountain, from Hidden Villa Trailhead and Rhus Ridge Trailhead. The park also provides opportunities for bikers and equestrians with cycling and equestrian trails and there is a large equestrian staging area. Bikes are only permitted on paved trails such as the Rancho San Antonio Trail. Horses are limited to the staging area the Coyote Trail, a;though horses are permitted on most trails within the Open Space Preserve. The South Meadow area adjacent to the staging area has a water trough for horses. The North Meadow area, across Permanente Creek from the parking area, has four tennis courts, a few picnic tables, and barbecues. Deer Hollow Farm, managed by the City of Mountain View, has farm animals, making it a great family activity. There are multiple parking lots in the park, however the parking lot can get crowded on weekends so it is best to get there early. Dogs are not allowed in the park. Hours: 8:00 a.m. – Sunset

This is a great short hike! Not too hard, beautiful scenery, tons of shade. I went on a Sunday afternoon and it was pretty busy but not crowded once I got past the first 1/2 mile or so. It had been raining all week so the trail was pretty muddy but not nearly as bad as I thought it would be!

Good trail. Has just about everything. It’s steep as you begin for 1 mile on Rhus Ridge upto Mary Davey Memorial, then a descent into the San Antonio Preserve via Chamise Trail. This will lead you to Deer Hollow Farm. There are water taps near the farm. The climb on your way back will be gentler, spread over 2.5 miles or so. Some parts of the trail are shaded, but not all. Great views at the top, on a clear day/evening.

Great trail to do with light rain since it is packed well and somewhat paved. Decent inclines and saw a fair amount of people. Shaded for the most part.

I would recommend this trail for a short, but strenuous hike. Views of the valley and a green rolling hills.

Nice and easy hike. Not much elevation. free parking lots.

This is not the type of trail I enjoy hiking. The first half of the trail is packed with people. There are roads throughout the park so you’re walking alongside roads rather than true trails. And there are so many trails, you have to consult the map every 10 minutes to ensure you’re on the right one. This isn’t a park or trail I want to visit again.

Easy walk, lots of paths, decent views, but no parking

Very suburban and crowded. Nice once you get on the smaller trails

Hike counterclockwise, and you will be fine. There are almost no people for about 1.5 miles after the initial 2 miles or so, if you go that way. Lots of shade once you are past Deer Hollow Farm too. Good for a 1.5-2hr afternoon hike

Suitable for family and kids. Make sure to have all trails map handy as there are lots of forks and waypoints in the path

Such pretty view and kind deer.

Very well kept trails. Not so crowded. Steep slopes at beginning of Rhus Ridge and at end of Black Mountain trails. Beautiful sceneries of trees, meadows and the Silicon Valley. Roughly about 9.5miles long 3.5hrs walk.

Very pleasant in the winter if not raining.

In no way is this trail system lightly trafficked. People are going to be on every section of this loop. With that being said, once you get about 3-4 miles in it does thin out but you still can’t go for more than 10 minutes without coming along someone else. Hiked counterclockwise and definitely recommend that.

This is the single most crowded trail system I've ever tried to hike on in the Bay Area. There are at least 4 massive parking lots, all of which will be full on a weekend with a long line of cars trying to get in. The trail is hardly better – you're practically shoulder to shoulder with others. It does get better the further you out you go, but it still ranks as way, way too crowded for my tastes. There are so many other trails in the same area that are practically empty, I'm not sure why anyone would go here.

Perfect way to spend Thanksgiving Day! The view at the top is spectacular...

Nice trail, but definitely be careful of mountain lions since there are lots of encounters.

Great hike close to town. Mix of woods and chaparral. Often see birds and bunnies. Lots of lizards on warm days. As noted, first and last sections are so lucky steep.

Hard to find parking on weekends but can park at Foothill College.

It gets harder to keep up your energy at the end but it’s definitely worth it.

This is my favorite trail from back home to solo hike! Trails are really nicely done and the hills definitely make sure you’re working hard the entire time. If you have the energy, I would recommend hiking up to the Black Mountain Peak for really great views and a different sort of terrain!

Really enjoyed this hike. Took about 4hrs to complete. Started at 7:30am..

the first one mile is mostly exposed so are first two miles of the return loop. the hard parts are all in the first half of loop. once you reach the top power transmission tower then it's all downhill and you can enjoy the view. if you have enough strength then it's worthy to continue to black mountain tower for 4 more miles round trip.

Did the hike this afternoon. Was planning on just doing the PG&E trail but said what the hell when I reached the top. I left at 4:10 and reached the top of PG&E in just over an hour. I jogged about 40% of the way. Thought it was a bit late and was short on water but figured I could do another 2 miles without too much difficulty. The trail narrowed and was steep from the get go. I'm 54 and can keep a decent pace (I think). I met two young girls along the way and was surprised at their speed but one said she ran x-country for her high school. We decided to go to the top together despite the late hour. I was concerned about possibly having my car stuck inside the gate over night if we got back too late. 1 mile from top of PG&E took about 35 mins. I thought it was a butt kicker. We could see the radio towers a good 3/4 mile from the top and I was about to turn around, thinking we wouldn't make it back til 8-8:30. The young girls proceeded...I wasn't going to drive home with a gut wrenching feeling of defeat so decided to finish it. We made it to the towers at about 6:15. A good very tough hour for the last two miles. We high fived and took a few pics and promptly headed down. We kept a good pace. I was depleted of water but one of the girls gladly filled my empty bottle. Due to the steepness it was nearly impossible to run. Made it back to the top of PG&E just after 7. We returned via Wild Cat and were finally able to pick our speed up after a 1/4 mile or so. We were trotting at a good pace as the sun had set and the full moon came into full view shortly thereafter. It was dark at the top of Wild Cat and we needed our flash lights. Too dark, steep and tired to run by then. We went through the farm and finally made it back to the parking lot just before 8 where I was greeted by an angry Ranger Ken who proceeded to give me a lecture, along with a 45.00 ticket for being late. I didn't give a shit. Was glad I went to the top and happy the girls gave me the extra push I needed. This hike is 12 miles from the parking lot. I would call it bit of a butt kicker. Doing Whitney in a few weeks so this was a good practice run, albeit not at elevation.

There's a big parking lot, but this is a popular staging area, so it gets crowded fast. The trail is dirt road the whole way, with power lines and views of the bay. It's a nearby neighborhood tromp with a little bit of elevation and distance, but a pretty mediocre hike otherwise.

♥️♥️♥️

To reach black mountain, there are three prominent trails. One is via hidden villa, second one is via Rhus ridge and the third one is via PG&E trail.

This trail (3rd) is less common due to the elevation gain being close to 3200 feet and is 12 miles total hiking distance. It is a good hike and gets challenging on the last two miles of ascent i.e. 5th and 6th mile. This hike is a must do in bay area before going to Yosemite hikes like upper yosemite waterfall hike or four mile hike etc.

When you reach the top, don't get dishearten by the communication towers. Rather, take the monte bello road towards the opening and you will be pleasantly surprised with the view of pacific ocean to west, San Francisco city to north, Lick's observatory in the east and mnt umunhum in the south. Also, you will get a good view of the silicon bay area.

I recommend this hike.

Good, challenging hike. I did it clockwise and I'm glad I did (though there was some steep downhill from the high point). I like to get most of the climbing out of the way earlier rather than later. I also appreciated that there's a fair amount of shade and cool breezes on the climb, since I was hiking at the hottest time of day. I'd hesitate to do it on a particularly hot day, but it's a good choice when it's normal-to-cool. The addition of Rogue Valley Trail was a nice way to extend it: a fairly gradual downhill from the ridge and then a flat final mile or two. I'll be doing this route again!

It is a decent trail and is easy to moderate. I started at 3 PM and hardly found anyone on track as compared to morning counterpart. Initial trail has buzz of electrical lines which is distracting to an extent but the ascent keeps you occupied. There isn't any scenic view apart from the valley view which points where the concrete jungle is. Path is well marked and in between you get patches of trees which is a real solace in hot sun. After first 4 miles with the elevation gain of 1.7k feet, it is normal decent back to start point.
