My favorite trail, we generally go counter clock wise but beware, it's a steep and steady climb to the top! Make sure to pause for breaks, turn back and enjoy the views. At the top it gets mistier and cooler which feels nice. Then you'll go down in the forest for a long while and I always finish off by letting the dog refresh and play in the river at the bottom. Enjoy (and don't forget your masks cause some paths are very narrow)

Wonderful hike! Following advice of other reviewers we went clockwise and it was definitely the right move view-wise. Short side trail to peak is not well marked so make sure not to miss it! Lower area quite crowded with many people not wearing masks but fairly sparse and more masks as you get higher. Descent from the peak on Spring Ridge trail was very quick, maybe 45 minutes compared to 2.5 hours coming up Hamm Gulch.

It's a nice trail which has a little but of everything. The wildflowers were quite nice this time of the year.

Nice warm day. Unfortunately no wind in the exposed area! Beautiful carpet of California poppies along Anniversary Trail with wide view of the Bay and Mt. Diablo in background. Many other wild flowers still in bloom. Best direction, in my opinion, is clockwise. Up Hamms Gulch and down Spring. Everyone I met was socially distancing. Some bikes to watchout for. Also there are some benches along the route so you can stop and admire the view. Very uplifting in this time of sad news.

Windy Hill is... windy! Weather was sunny and warm in the parking lot. With a cold front coming through, the wind was blowing 20+ mph and cold at the summit. Bring layers if there's weather. Definitely recommend the clockwise trip. Hamms Gulch Trail runs through dense forest and is very peaceful. The views at the Windy Hill peak are terrific, with the bay on one side and the ocean on the other. Spring Ridge Trail is a scenic descent back, with great views of Stanford and the bay, and even a couple of peaks of San Francisco.

If you’re a trail runner or any kind of endurance athlete this is a great place to train. Trail is well laid out and easy to follow so you don’t have to break your pace much to figure out where you’re going. Solid loop with a nice variety of woodsy/covered areas and open meadows. I started at the Windy Hill Summit so the way out was mostly gentle elevation changes. Last two miles back to summit however is basically up hill the entire way, so a good way to power out your training. Will return

A beautiful hike on a spectacular day. Definitely take Hamms Gulch to Spring Ridge ca the other way around. Spring Ridge is in the sun most of the way, which gives great views, but is hot.

Nice trail in the Spring with everything green. Push on to the top for views of the Bay and Coast.

Hiking Hamm’s Gulch was a serious workout—long, relatively steep uphill. Lots of tree cover. Some nice views. Quite muddy in January. Views from the top in particular were really nice after a great workout. Taking Springs down was not much fun. It is basically a wide dirt road without much to look at or enjoy.

Great trail! Doggie and kid friendly. A bit chilly at first, so best to wear layers. Lots of cool mushrooms to see. Careful of ticks and poison oak along the trails. We saw a lot of both!

Great trail! You can see the City in the distance from the hill! If you’re doing the loop starting later in the day, where you might still be out when the sun goes down, you may want to start to the left on Spring Ridge Trail, instead of right Betsy Crowder, cause going the BC Trail (also pretty steep) is more open, while the SR Trail (switchbacks) is mostly wooded. Trailhead had informational signs about mountain lion sightings, rattlesnakes and poison oak.

One of my favorite trails. It’s shaded and very scenic along the way. It’s high elevation so be prepared if you haven’t hiked before. We did Hamms Gulch and then continue to Spring Hill trail. It’s perfect to hike this trail at this time. Cool breeze and beautiful fall colors are also starting to show :)

Great hike! I recommend to start on Hams Gulch side early in the AM due to trafficked trail and sun.
