North Trailhead Of Sawyer Camp Trail at San Francisco Peninsula, California, Millbrae, California.

This is a pretty trail for biking or jogging. Mostly flat with a small hill at the north end of the trail. The trail used to be very popular and crowded on weekends, but construction over the last several years (since 2010) closed the main road to the southern trailhead and also closed the main parking lot. Now days, the trail is far less crowded. Construction was supposed to end in 2012 but that has now been extended to at least 2018. If you're biking to the trail, watch out for construction trucks on weekdays on Crystal Springs Road.

Great sunny hike. Flat, good for biking or walking. Beautiful lake.
