Past the Lovers Lane footbridge (pic 4) onto a trail between two streets, and up a short stairway to the Main Post at Inn of the Presidio. Behind the Inn is the east trailhead for the lower Ecology Trail.
This shady trail soon merges into the upper Ecology Trail (pic 5) where you can either continue up to Inspiration Point Overlook or take the stairs down (69 steps, pics 6, 7) to visit El Polin Spring (8, 9), and up the accessible ramp on the west side (pic 10).
Pic 11: Bay Area Ridge Trail above Arguello Blvd.
After hoofing it offtrail a bit to the upper Park Trail (12 thru 15) continued up to the winding wood steps (about 98) that climb through the forest to the Cemetery Overlook (constructed 2009): 16 through 28
A view from the overlook: pic 29.
East from the overlook is an old, “wilder,” trail that’s another of my favorites, pic 30. If you love forested trails, check this beauty out sometime. It winds down to the Post Chapel. At the chapel, you can descend the stairs to the Main Post.
