Rancho San Antonio County Park

Miles of well-maintained trails for hiking and running with some gorgeous views . Come early, it can get really hot during summer time.

Lovely place. They have a farm with different animals. Sometimes you can see deers . Trails are not very strenuous. But be aware that PG&E trail is longer than stated 3.7 miles.

I love this place, but peak times are 9-11 AM. It will be almost impossible to find parking . But you can drive a little past the parking lot to find parking in the residential neighborhood .

Good for hike . Only parking matters. For hiking , it is not hard to get through. Had a lot fun.

Great hiking trails and beautiful views from up high. Parking is a challenge though.

This is another goodie when you are looking for something to do that isn't just walking. They have tennis courts , picnic areas , and best part...a cute animal farm !

Nice trail . There are trees everywhere which much needed relief from the sun. Parking is a big problem, so try and get there early.

Awesome park ! You can see people flying model airplanes, play by the creek and see some farm animals as well as various hiking trails .

Great place! Some treks for sporty adults, some for people with children or even trolleys. Everyone will find a path for them.

Time for easier parking : early in the morning (before 9:30), during lunch (12:00 to 1:00) and late afternoon (after 3:00).

Awesome place to walk around. Check out the farm and its animals!

Has 4 parking lots , but still couldn't find parking at 6:30 am on a Saturday. There is a residential community next to it, where you can street park

One of my most favorite places!!! Great if you're looking for a nice walk with friends or, if you want to challenge yourself, pick a trail and get going! My favorite trail , Upper Wild Cat Trail .

More parking than by most other trails in the bay and many trails to choose from

Great place for a not difficult hike , excellent for kids with bikes ! We will go back!

Hike to the top of the PGE trail to get an awesome view of the valley and the bay . Takes about 2-3 hours start to finish. Enjoy the wildlife you'll see on your way.

Fantastic views at the top of the trails ! Worth the hike ! Shaded trails and well maintained.

Just 45 minutes from San Francisco, this preserve has 23 miles of hiking , biking , and horseback riding trails .

Hike the PG&E trail early or late, to avoid banking in the sun. 4000 feet cumulative altitude gain.

Looking to get in shape and see some great scenery.. This park is wonderful for hiking and/or trail running. The PG&E trail will take about 3.5 hours and will put your daily calories in a deficit. Read more

Great place to get outside for a walk. Parking is tough.

Amazing place. Make sure you dont get lost it can be a little consuing at start

Great for an easy hike or mountain biking to get out into nature.

Beautiful place for a hike , but lately it's been hard to find a parking spot .

Excellent place for an easy hike to get out into the nature!

Go on the new Quarry Trail at the peak of PG&E trail to get access to Black Mountain .

More animals out when you go early. Spring 2013: new baby goats and calf at deer hollow farm .

protip: after your run, head to the nearby Trader Joe's for some recovery chocolate milk

love the PG&E trail , great workout, great views , only bad thing is the buzzing of the power lines .

Great place to run or hike . It can get crowded

Move over Snakes, it’s the year of the Horse! Race on over to Westfield Valley Fair and celebrate Lunar New Years with fun cultural festivities on 2/8/2014. Read more

Hiking is good for you. The wildlife is awesome and the air is clean . Be sure to bring large water bottles -- you can refill easily however you want to have some with you....

Parking can be difficult, but great trails .

Get here before 8am on the weekend . Parking is always difficult here.

It's a nice hike . Wear comfortable boots or shoes .

Lots of gaggles of turkeys and the deer had very close personal space on the trails today

Great place to go hiking ????

Weekends get very crowded .

Wonderful running spot!

You might see some wild turkeys

The only thing you need to know about Mountain Lions: Hike with someone SLOWER THAN YOU!

Hahahahahxjndjf

Biking paths are limited, most trails don't allow mountain bikes :(

On weekends go early, parking sucks

On weekends you need to get here before 6:30 am or u won't get a parking spot !!!

Good hiking trail

Hike in winter to avoid rattlesnakes .
