George F Canyon★★★★★A quiet hike along a seasonal streambed. Shady for the first part, then opens up. Beware of poison oak. City view at the summit. Birds, rabbits, butterflies.
Linden H. Chandler Preserve★★★☆☆Hilly, with not much shade except in the lightly wooded areas along the intermittent streambeds. Higher areas have clear views of the LA Basin and the golf course next door.
Malaga Canyon ReserveGorgeous views from the trailhead that I found (which was closed). I need to see if the other trailheads are open.
Prickly Pear Trail★★★★☆Short loop with some steep sections. Lots of cactus. (Keep your balance!) Nice views of the ocean and Point Vicente Lighthouse.
