This street is Villarrica Way.

There is a little-known walkway with several flights of stairs from Armada Terrace in San Diego, California to the end of Armada Place. It is not shown on Open Maps or Google Maps. Unfortunately, it is not visible on Google Earth because of trees and other vegetation. However, it is described in local hiking guides, and I have posted pictures and coordinates temporarily at

The Bicycle and Foot Path around Lake Murray Reservoir is signed as "Lake Murray Reservoir Maintenance Road".

There is a paved pedestrian/bicycle path from the north end of Dain Court to the south end of Golden Avenue in Lemon Grove, California. It is shown on Google Maps as "Secret Path of Lemon Grove", but it is signed as Mariposa Lane. It is similar to many other paths that are shown on OpenStreetMap. Additional information, such as photographs and coordinates, are available.

It descends to the south end of Ellsworth Lane in Santee, a distance of approximately 0.04 miles. It is very similar to other paths and stairways that are shown on OpenStreetMap. Photographs and a GPX track of the path and stairway are available.
