More essential treks to take

I was disappointed that my two favorite hiking venues -- Placerita Canyon State Park and O’Melveny Park -- were overlooked in “10 Essential Hikes” [March 15]. Both locations have many trails of various difficulty.

Thank you for “10 Essential Hikes.” I’ve only known of a few places in Southern California that are truly urban escapes (one of my favorites is Vasquez Rocks). This is a great guide to finding a few more.
