Best overall hike
Turnbull Canyon, Rattlesnake Ridge & Sumac Trail Loop
Whittier Hills North Of South Whittier • Steep Canyon And Ridgeline Loop With Big City Views • Signature Whittier Hills Route
A classic Whittier Hills loop that mixes punchy climbs, rolling ridgelines, and sweeping views toward downtown Los Angeles and the San Gabriels.
From the Turnbull Canyon Road trailheads, you can stitch together Rattlesnake Ridge and Sumac Trail for a loop that feels surprisingly wild this close to suburbia. Expect exposed sections, steady climbs, and enough side trails to tailor the distance to your energy level. Go early on hot days, bring plenty of water, and stay aware of mountain bikers on the wider fire roads.
02
Most popular local climb
Hellman Park Trail
Uptown Whittier Foothills • Short, Steep Hill Hike With Quick Payoff Views • Go-To Evening Workout Spot
A straightforward but steep climb that rewards you quickly with wide-open views over Whittier, La Mirada, and the coastal plain.
Hellman Park’s main trail heads straight up the hillside on a mix of dirt path and rustic stairs, making it a favorite for locals looking to squeeze in a quick workout. Once you crest the initial climb, you can wander the ridgeline paths for sunset views or loop toward the oil roads for a bit more mileage. Parking is tight at busy times, so be patient and respectful of the surrounding neighborhood.
03
Best canyon escape
Sycamore Canyon Trail
Whittier Hills Near Friendly Hills • Shaded Canyon Singletrack Through Coastal Sage And Oaks • Best For A Cooler Mid-Day Hike
A quieter Whittier Hills option that drops into a leafy canyon, offering more shade and a tucked-away feel than the exposed ridges.
Sycamore Canyon is a nice change of pace if you’re used to the big climbs at Turnbull and Hellman. The trail winds gently through a drainage lined with sycamores, oaks, and coastal sage, with side paths that let you pop up to the surrounding ridges if you want extra elevation. It’s a good pick for hikers who prefer softer grades, birdwatching, and the sense of being tucked into a small pocket of wildland.
04
Best longer loop
Powder Canyon Loop via Skyline Drive
La Habra Heights And Hacienda Heights, East Of South Whittier • Rolling Oak-Studded Hills With Wide Dirt Roads And Side Singletrack • Best For Longer Weekend Outings
A roomy network of trails and fire roads that lets you build anything from a mellow stroll to a half-day loop with constant views.
Powder Canyon sits just a short drive east and feels more expansive than the tighter Whittier Hills canyons. The main loop follows broad dirt roads through grasslands and pockets of oak, with options to branch onto singletrack or continue along the Skyline trail for more distance and elevation. It’s a solid choice if you want space to roam, less crowding, and a hike that can grow or shrink with your group’s energy.

Easiest all-ages option
Whittier Greenway Trail
Through The Heart Of Whittier • Paved Multi-Use Greenbelt Path Along A Former Rail Corridor • Most Accessible Option
A flat, landscaped path that’s ideal for relaxed walks, jogs, and stroller-friendly “hikes” close to South Whittier neighborhoods.
The Greenway Trail trades dirt for pavement but delivers easy access, gentle grades, and a surprising amount of greenery threaded through town.

Start from one of the access points closest to South Whittier and make it an out-and-back, turning around when you’ve had your fill.
