A stroll around Mountain Lake took me under the highway overpass to the other side of Park Presidio/Veterans Blvd. Up the 103 steps to the Marine Cemetery Vista (pics 1 and 2), then to the top of Battery Caulfield Road at Washington.
Just before reaching Immigrant Point Overlook, ascended the Anza Trail to curve round on the south side of Rob Hill Campground a short distance.
At the southeast edge is a short stairway down. Directly across (at the yellow hydrant) is a short trail to Fort Scott and its community garden. Pics 3, 4.
A few yards to the right of the steps is the trailhead for the new BART extension (fifth pic).
Hadn't hiked this particular area in a while; was impressed with the nice job they've done with this area. A little way in is a trail fork with a sign (sixth pic) and a slightly higher trail for both bicyclists and pedestrians (pic 7). The one I continued on the first time is posted for pedestrians only (pic 8). Current pix of this beautiful, secluded, forested trail: 9, 10, 11.
My planned destination the first time, a familiar route to the east out to the Park Trail, was closed because of "tree work," so doubled back to the west up a familiar trail section (12th pic), sunny and open for a few yards. The also-familiar end of this wasn't far from where I'd started up off Washington, the old wine bunkers, kids' playground, residences, and community garden just ahead on Compton.
Later checked out the multiuse trail. Both these short trails come out at the same place, the end of Compton (pix 13, 14). From here one can also walk over to Washington, a short distance alongside the residences to Battery Caulfield Rd.
A couple of current pix (15, 16) of the replacement steps up to Inn at the Presidio/Main Post sans the orange flexifences.
Including here also a few of the Batteries to Bluffs Trail (473 steps) from a week or so ago: 17 through 20.
