Windy Hill Preserve has been one of my favorite places to hike since I was little. The entrance is located just off Portola Road in Portola Valley and is marked with a big sign. The hike is pretty much straight up and down and you can choose between a switch back route in the shade (Hamms Gulch Trail) or a more exposed straight up approach (Spring Ridge Trail). At a good pace, its about 1hr from the base to the top. The switch back route takes a bit longer. Dogs are allowed, although only on leash. The views from the top are absolutely spectacular! I like to bring a little picnic although it tends to be very windy (hence the name). Here’s the marker from the very top- Spring Ridge Trail + Anniversary Trail (another 0.7 miles).
It is steep so come prepared with good hiking shoes- you may also have sore gluts the next day! Somehow we made it 🙂
Enjoy! And for more information and a downloadable map check out their website. ~B
