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

beautiful forested trails. lots of people in the beginning but much quieter as you get onto the actual loop

This is my first hike I’m used to walking long distances. But never tried hiking... really enjoyed... for a beginner, try to take the route which goes from the deer hollow park and at an intersection you can merge to the Stephen abhors... instead of taking the steeps... all over nice experience

Walked with Two adult daughters. Fantastic pre-thanksgiving walk. Some hills, beautiful trees and great energy

Went with a large group of 14 kids. The loop was pretty decent but go early for parking.

Great short climb. Wide trail in good condition.

nice view of the bay

Fragrant and quiet hike. Very well maintained trail. A little steep but not too bad. Alternating sections of sunlight and deep shade. Not a lot of wildlife except a few birds and rabbits. Nice occasional views of the valley and the bay bridges below. Had to turn back due to time before reaching black mountain summit, managed 8 miles in 2.5 hours. Saw only 4 other parties the whole time.

Top section is closed due to mountain lion sightings.

Well Maintained trail with good shade

Steep but shady in the afternoon. Nice intermittent views. Great for a fall hike.

This is one of my go to trail runs. Love the balance between up and down. Great views! Always a very clean and well marked trail. Please move for trail runners :)

Easier than mission peak. Open trails. Good quality.

This is a pretty easy trail. I think you could take kids with you on this one. Lots of families and a cute little farm to see.

clean trails and beautiful views.

Toasty and steep. Great trail run.

great hike. first and last mile are the most strenuous ones. it took me 2.5h round trip and it was not crowded during the evening (finish at dawn).

Trail was good. It might be difficult to get a parking but try to come as early as possible. Lot of shade and traffic was moderate .

Clockwise is much better

Good for trail running with some shade! Did it in reverse to have a nice downhill stretch.

Just completed Oct 2019. I arrived 7:45am on a Saturday and the car parks were already full so bear that in mind. It’s a fun trail and a very good workout. The first 3 miles up is on a wide track and is busy with people. The last 2 miles to the summit is on a narrower, more interesting trail which is wooded and very steep in places. Remember to look behind you for the views. When you get to the top, there is a communications installation that is pretty ugly but walk an extra quarter of a mile or so (keeping the masts on your right) and the hillside opens up with views all round. The wide track section gets a little boring on the way back down but that’s out and back trail routes for you.

Nice trail. Lots of shade. Would highly recommend to other hikers.

Great workout hike! Views are pretty, a lot of shade, not crowded at all.

two sections of up and down, cute farm in the middle part of trial, mostly with shades, light traffic on Sunday morning

One of my favorite hikes. Lots of shade going clockwise. Little steep but smooth heading down the other side with the farm to greet you at the end. Lot of people here and parking can be hard to find in the morning. Saw birds, lizards, squirrels, deer, turkeys, and horse riders. Great views and atmosphere.

Lots of flies. Otherwise a fairly decent hike.

Beautiful hike. Would do again. A couple of parts were a little narrow so it might not be ideal for a big party but otherwise it’s my new preferred 10 mile+ hike in this area.

Overall, an easy to moderate hiking trail with approximately 75% shade to 25% unshaded areas. It has plenty of views of open pastures and rolling hills with a nice vista point of the bay at the midpoint. Depending on your level of experience, it should take anywhere from 1.5 to 3 hours walking/jogging.
