Windy Hill Loop via Hamms Gulch Trail
This is a moderate 7.5 mile loop trail to Windy Hill in Windy Hill Open Space Preserve, going up 3 miles mostly in the sun, coming down mostly in the shade.
This trail goes by Sausal Pond.
This trail can be cold and wet when there is heavy fog, so be aware of the weather.
Park in Windy Hills Parking Lot in 550 Portola Rd in Portola Valley. Start by taking Betsy Crowder Trail behind the bathrooms.
then head up on Spring Ridge Trail. Anniversary Trail and Lost Trail will take you acrodd until you get to Hamm's Gulch Trail to descent. You will end up back on Sprint Ridge Trail along Corte Madera Creek, but this time you want to head toward the parking lot on Portola Road and Sausal Pond instead of going back up on Spring Ridge Trail.
There is a bathroom also at the parking lot on Skyline Blvd close by Windy Hill which can come in handy.
5: Good for older children that can walk 7-8 miles with moderate uphills.
