I brought my camera and pedometer hiking on the northwest corner of the city last weekend.... Here's a picture of some of Lincoln Park's winding trail, which I took all the way to the edge of the cliff that provides a great view of the west side of the golden gate bridge (you may just be able to just see a couple people in the pic viewing from the cliff). It's a beautiful place, and you can look down and see deathly waves hitting the rocks along most of the path...
