Windy Hill offers sweeping views on the San Francisco Bay from its steep trails. The difference in elevation between its highest and lowest points is about 400 m (1300 ft). Windy Hill's 3 main trails that run roughly in parallel provide equally attractive routes to ascent or descent the park. From this trail network visitors can create various options for loops or out-and-backs: Spring Ridge Trail, mostly straight up through meadows with great views, and Hamms Gulch Trail and Razorback Ridge Trail with both lots of switchbacks mostly through dense forest. At the top of the park these trails are connected by the Bay Area Ridge Trail, and at the bottom by Eagles Trail, connecting to Sequoias Trail and Ridge Trail. The park is a local favorite for hiking, trail running, mountain biking and horse back riding (about 65% of the trails are multi-use). Hours: Open half an hour before sunrise to half an hour after sunset

What a beautiful trail loop and great workout! Hamms Gulch was busy, but the scenery - mossy redwoods, lush foliage and babbling brooks - made up for it. Getting to Eagle Trail was a treat with a meandering flowing stream along the way. I didn’t even notice the road just above and took a short stop to dip my feet. And Razorback Trail up to Lost Trail was really quiet and a good challenge.

Great trail for running. I like hills. I started counterclockwise. Harder workout and the spectacular views were behind me. If you like hill challenges I recommend this way. If you like great views then clockwise the trail.

Beautiful trail, somewhat narrower than expected, overgrown in places, and muddy towards the top. A bit above my skill level but completed the hike down and back.

Beautiful shaded trail. Dog friendly (but must be on leash). Three quarters of the way to the top there is a washout, which you can climb over but today (6-1-19) it was still pretty thick and slippery with mud. Lots of poison oak. Bring water!

Hamms Gulch is a great trail with lots of shade. Dogs allowed but must be on a leash. As of June 1, 2019 there is a washout about 3/4 of the way up, but if you are careful, you can climb up and over it-it was quite slippery with deep sticky mud still today. Lots of poison oak on both sides, all the way up and some thistles growing into the trail in places. Bring plenty of water. The front side (Spring Hill?) is very exposed/sunny. Parking at Windy Hill parking lot can be tough on the weekends, so go early!

Bit muddy in places. Excellent wildflowers for June 1!

Great loop! Not too much shade on the first exposed half, but coming down Hamms Gulch was beautiful in the trees. There was a creek at the bottom that was great for the dog to get a drink as well!

Take Hamms gulch up, good views, watch out for ticks and poison oak

Great views and open space highly recommend.

Great hike close to Palo Alto. A little tough going up, but great vegetation, redwoods and amazing views of the Bay Area at the top. On a clear day, you can see from San Francisco to San Jose. Hiked in mid-March and the weather was good. A little warmer than usual.

It's a straight upwards climb, and definitely very windy at the top (and along the way). Arrived at 9:45 AM on Saturday of Memorial Day weekend. Lots of cars parked along the road but I pulled into the parking lot and managed to get a spot as some people were leaving at the moment I pulled up. On the way out, I saw a sign indicating that parking was not allowed along the road (though maybe only in certain parts as I saw another sign along the road that said cars had to be pulled off the road all the way). The sign in the parking lot indicated that there's an overflow parking lot about 0.4 miles away. When I left the parking lot around 12:30 pm, there were many spaces open in the main lot by the trailhead. I'd call this a highly trafficked trail. People had their dogs off leash even though they're supposed to be leashed. The views of the hills from the top were nice but other than a quick look around, there isn't much to do up there – no benches (though there are a couple benches along the way). Recommend trekking poles if you have them to protect your knees and get stability on the loose gravel in parts on the way down.

Fallen tree/wash out 3/4 through trail. Has river 1/4 way in, good if alpine training. Would be great if steeper. (DM me if you know trails nearby that fit this!)

A beautiful trail. Has some “enchanted forest” moments!

Nice trail and lots of wildflowers this time of year! Would recommend hiking up on Hamm's Gulch (more shaded) and down on Spring Ridge.

Parked at the Portola Rd trailhead and decided on a counter clockwise direction. The ascent is tough for the first 2 miles or so until you reach the top of Windy Hill. No shade and hard scrappy ground. Beautiful views of the entire Silicon Valley from the top though. Go on a clear day!! That’s about the best pet of this loop. The Lost Trail portion is pretty, even a bit magical looking at points. The rest....meh. If you want the views without too much of an ascent then park at one of the Skyline Blvd. trailheads. It’s a short hike to the viewpoints from there.

went up hill on spring ridge which has no shade, steep, but nice view; it is very windy at the top (consistant with its name); went down hill via anniversay and hamms gulch which offers lots of shade and gentle slope. one point on hamms gulch has mud slide and the pass becomes climbing on the sidehill - not dangerous but not easy. overall, very pleasant and good work out
