A short hillwalk up Battery Caulfield Road, now with safer pedestrian walkways alongside the street, with a left on Washington at the top, leads to Immigrant Point Overlook (pic 3) where the Connector Trail (208 steps) descends through the forest to Lincoln.
Connector Trail: 4 thru 9.
Crossing at the crosswalk, bypassing the Sand Ladder's 250-ish up-n-back steps down to Baker Beach, a short sandy trail (pics 10, 11, 12) leads to the west trailhead for the Batteries to Bluffs Trail (473 or so steps).
Batteries to Bluffs west to east:13 thru 28.
