Windy Hill Open Space Preserve is located west of Palo Alto in Portola Valley.
The hike begins at the Portola Road parking lot, about 1 mile west of Alpine Road. We'll meet at the end of the parking lot near the trailhead. We'll walk about 3 miles up Spring Ridge Trail to Anniversary Trail, pause for lunch to take in the panoramic views, and then return via Hamms Gulch Trail.
This hike is a loop of about 8 miles, with an elevation gain of about 1,200 feet during the first 90 minutes. Duration will be about 3-1/2 hours, depending on the number of pauses.
Important: This hike will be too difficult for some hikers. Please do not join us if you have difficulty climbing hills, or if you cannot keep a steady pace of at least 3 miles an hour. (Learn more.)
