Astra Lumina★★★★★Nighttime walk through botanical gardens and a series of immersive light-and-music shows that you can take at your own pace. Definitely worth it!
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.
Hopkins Wilderness Park★★★★☆A good place to bring your kids or just take a shady walk in something that feels like nature. Lightly wooded, some hills, trails, a stream and a duck pond, plus picnic areas and camping.
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.
Madrona Marsh Preserve★★★★★One of my favorite places to walk in the South Bay, the preserve is the last remnant of seasonal marshes that once covered the western part of the LA basin.
Malaga Canyon ReserveGorgeous views from the trailhead that I found (which was closed). I need to see if the other trailheads are open.
South Coast Botanic Garden★★★★★Big enough to feel like you could get lost (but not big enough to get lost), packed with trails that feel like walking through nature, surrounded by more structured gardens. Great for events, families or just getting out for a walk.
Valmonte Trail and Frog Creek Loop★★★★★A nice, easy loop trail. Hilly, with plenty of shade in the wooded areas along the stream beds. Lots of side trails.
