The address on the Yelp listing is way off, hence the map is off.
The first reviewer's description of the reserve is correct in all regards except that Filiorum Reserve is in Rancho Palos Verdes, not Rolling Hills Estates.
It's just under 200 acres above Abalone Cove, adjacent to Portuguese Bend Reserve.
The Silver Spur address is actually a commercial building near the Peninsula Shopping Center.
The pvplc link under the Yelp map suggests accessing Filiorum via McBride Trail. (Take Highridge to Ocean Terrace Drive & go to the end of the street. Always plenty of unlimited, free street parking here.)
This takes you to Filiorum through Three Sisters Reserve.....not easy. I would not do it twice, lol. That's probably why nobody's parking there.
Re the other trail into Filiorum:
Rattlesnake Trail marker, just down the sidewalk from Del Cerro Park, is indeed easy to miss. It's small. But it's there.
Parking is a lot easier on Ocean Terrace than anywhere around Del Cerro Park. Ocean Terrace is a short driving distance on Highridge from Del Cerro.
But....parking near Del Cerro/Rattlesake Trailhead is not too bad on a weekday. So I'd do that.
Note that Del Cerro Park itself now has restricted, permit-only parking. Park on Crenshaw. On a weekend, good luck, you'll need it, in addition to a miracle....to find a space. read more
