Pillar Point is a hot spot for birding year-round. We should find a variety of resident birds and migrant shorebirds. Most of the walking will be on fairly level dirt trails, but if time permits, we may hike up onto the bluff top for a better view out to sea. Scopes will be useful here, so if you have one, bring it along. A primitive restroom is available at the parking lot.

Directions: The harbor is located just west of Coast Highway One, 18 miles south of San Francisco and 4 miles north of Half Moon Bay. From Coast Highway One, turn west at the stoplight at Capistrano Road and continue along the north side of the harbor to Prospect Way. Turn left onto Prospect, then a brief jog right on Broadway, to an immediate left on Harvard Avenue. Proceed through the boat yards to the end of Harvard Avenue, then turn right onto West Point Avenue, which curves around a marshy area and heads uphill to an Air Force Radar Facility. Meet at the "West Shoreline Access" parking lot below the "Golf Ball."

Any bike is fine, but you should be prepared with binoculars, water, sunscreen, snacks and a biking helmet.
