Hamms Gulch-Spring Ridge Trail Loop

The route leaves the parking lot in Portola Valley and breaks off to the left as it follows the Spring Ridge Trail. The trail begins to gently climb uphill as private property sits off on the lefthand side of the trail and a pond sits on the right hand side, although it is mostly obscured by trees. The dirt trail is wide and used by horseback riders, mountain bikers, and other hikers. This causes the trail to suffer from erosion, and it can be torn up if it has been wet recently. Wildflowers can be seen on the side of the trail in the spring as the trail rolls gradually uphill. The trail continues straight ahead until the Spring Ridge Trail breaks off to the right and climbs steeply uphill. Go straight through the intersection and follow the trail until it crosses the private road roughly .2 miles ahead.Cross the road and continue straight ahead as the Meadow Trail breaks off to the left and leads down to the park boundary. Things can be confusing in this section as the Meadow Trail breaks off to the left and then breaks to the right again shortly after as it ascends into the meadow. Our path breaks off to the left and begins to descend toward the creek. The trail enters into the woods as the path drops to the creek as it exits the park briefly. If there is water running through the area, it can be easily overcome via a rock hop. While the Eagle Trail crosses the creek again to the left, the Hamms Gulch Trail begins to climb steeply uphill as it re-enters the preserve.The Hamms Gulch Trail climbs uphill toward Skyline Boulevard where more expansive views await. The trail works its way through the woods, which provide shade at all hours of the day. At roughly 1.9 miles, there is a bench where you can take a break and enjoy the views of the hills across the gulch. At 2.0 miles, the trail levels out for a little bit, offering a needed respite from the climb as it follows the ridge line. After a short distance, the trail starts climbing a series of switchbacks as views of Windy Hill can be seen, although obscured off to the right. At 3.3 miles, there is a side trail off to the right that leads to a small outcrop of rocks that offers views of the Stanford Dish area and the bay beyond.At 3.6 miles, the trail intersects with the Lost Trail and our path cuts off to the right as it levels out and works its way 1.1 to the Spring Ridge Trail. Entering a shrub lined corridor, the path follows the road for a little bit before meeting up with the Anniversary Trail at roughly 4.3 miles at a parking lot alongside Skyline Blvd. The Anniversary Trail wraps around the hillside as it makes its way to the summit. Great views to the east stretch out on the right hand side of the trail. A small trail goes off to the left that leads to the true Windy Hill summit. Great views of the bay area, the Windy Hill Preserve, and Santa Monica Mountains spread out before you. After returning to the Anniversary Trail, the route drops down to another parking lot along the road at 5 miles where the Spring Ridge Trail begins.The Spring Ridge Trail begins to drop steeply into the preserve on a wide, doubletrack dirt trail. The trail drops steeply, passing a spring suitable for horses but not humans, as it winds its way through the open fields. Wildlife can be seen feeding alongside the trail in the evenings. In steeper sections, the trail changes from dirt to gravel to help with erosion. Trekking poles help navigate the steep grades by taking stress off the knees. At 6.6 miles, the Meadow Trail breaks off to the right as the trail drops into the woods and the descent becomes less steep. A small connector trail to the lower sections of the Meadow Trail cuts off to the right at 7 miles. The trail finally levels out and cuts back to the right, following the lower part of the Spring Ridge Trail that you traveled on earlier. After about .6 miles, you are back at the parking lot and your car.
