This is a short, easy trail adjacent to the Lower San Antonio Fire Station, not far off Mt. Baldy Road, — it's immediately above the San Antonio Dam, on the road signposted Upland, which is Shinn Road, becoming Mountain Avenue at the county border, where the fire station is located. The area was formerly covered by eucalyptus trees, which burned in the 2003 wildfires. SInce then, the area has been cleared of eucalyptus and the native vegetation is being encouraged. There is plenty of it to see. This is an example of a location that in itself is not spectacularly situated, but is easy to access and offers a substantial variety of native flora. And there is a great view up the canyon towards Mt. Baldy, as shown below.
There is also a web page on this site describing the aftermarth of fire on the Joatngna Trail.
