01
Best overall pick
Turnbull Canyon Trail
Whittier Hills • Classic Ridge-And-Canyon Loop • Iconic Local Favorite
A Whittier Hills staple, this loop combines steady climbing, wide-open ridges, and big views toward downtown Los Angeles and the San Gabriels.
Starting from Turnbull Canyon Road, you climb quickly out of the neighborhoods and onto a web of fire roads and singletrack with plenty of options to shorten or extend your hike. Expect exposed stretches, chaparral-covered slopes, and a real workout on the steeper grades. Go early on warm days and be ready for limited parking at the trailhead.
02
Best quick workout
Hellman Park Trail
North Whittier • Steep Hillside Climb With Big Views • After-Work Leg Burner
A short, steep push from a residential trailhead to panoramic Whittier Hills vistas that feels like a gym session on dirt.
From the end of Greenleaf Avenue, the main trail shoots straight up the hill on a wide, often busy path favored by locals training after work. Once on the crest, you can follow the ridge for broader views or connect to longer routes along the Skyline trail. Parking is tight and shade is scarce, so many hikers time it for cooler evenings and sunset glow over the basin.
03
Best rolling loop
Powder Canyon Loop
Puente Hills Near La Habra Heights • Rolling Foothill Loop Through Grasslands And Oak Pockets • Weekend Moderate Loop
Wide paths and bits of singletrack roll through open hillsides, scattered oaks, and long views toward the San Gabriels.
Powder Canyon offers a mellower alternative to the steeper Whittier climbs, with enough up-and-down to feel like a real hike without being punishing. The loop feels surprisingly quiet given its proximity to town, especially in the cooler months when the hills green up. It is a solid choice for hiking with friends, dogs on leash, or anyone building up to the tougher local routes.
04
Best mixed-terrain outing
Fullerton Loop Trail
Near Downtown Fullerton • Mixed-Use Trail Through Canyons And Oak-Lined Gullies • Intro Trail For New Hikers
A popular multi-use circuit that strings together dirt paths, shady gullies, and brief neighborhood connectors for an approachable but varied hike.
Just a short drive from East Whittier, the Fullerton Loop is a go-to option when you want time on dirt without committing to a big climb. Expect a mix of sun and shade, bikes and the occasional horse, and plenty of locals using it for training laps. It is ideal for newer hikers learning how local terrain feels over a few hours on the trail.
05
Best family-friendly stroll
Sycamore Canyon Trail
Whittier – Puente Hills Preserve • Shady Canyon Walk With A Tucked-Away Feel • Relaxed Nature Walk
A gentler canyon route with more shade and a quieter atmosphere than the big ridge climbs above town.
Sycamore Canyon trades sweeping ridge views for a more intimate feel, with brushy slopes, pockets of trees, and a sense of being tucked away from the streets below. The grades are kinder here, making it a comfortable choice for families, casual walkers, and anyone easing into hiking. It pairs well with a short drive up into the hills when you want a quick dose of green without committing to a long day out.
