01
Best overall pick
Summitridge Park / Steep Canyon Trail
Northern Diamond Bar Hillside • Steep City-Park Ridge Trail • Best Quick Workout Close To Home
A short but punchy climb straight out of the neighborhood, rewarded with wide views over Diamond Bar and the San Gabriel Valley.
Summitridge Park feels tailor-made for locals who want a serious workout without a long drive. The main loop and offshoots climb quickly onto an open ridgeline, so you gain views almost immediately and can adjust distance and difficulty on the fly. Hit it at sunrise or golden hour for cooler temps and some of the best light in town.
02
Most family-friendly
Sycamore Canyon Park Trail
South Diamond Bar Canyon • Shaded Canyon Park Path With Creekside Feel • Relaxed Option For New Hikers And Families
A mellow out-and-back that slips quickly into a quiet canyon, with enough incline to feel like a hike but not enough to scare off beginners.
Starting from the lower parking area, the trail winds into a surprisingly peaceful draw tucked below the nearby streets. You’ll get a mix of pavement and dirt, pockets of shade, and a gentle grade that suits strollers, kids, and casual walkers. It’s the kind of close-in trail you can loop into an evening dog walk or a low-key Saturday outing.
03
Top long-distance route
Schabarum Trail (near Peter F. Schabarum Regional Park)
Rowland Heights / Hacienda Heights • Long-Distance Regional Trail Over Rolling Chaparral Hills • Best For Mileage And Training Days
A sprawling ridge and hillside route where you can stack on miles, rolling climbs, and open-sky views without getting too deep into the mountains.
Just a short drive west of Diamond Bar, the Schabarum Trail threads along hillsides above the neighborhoods, linking parklands and open-space corridors. Sections near Peter F. Schabarum Regional Park offer dirt singletrack, moderate climbs, and big-sky views toward the San Gabriels and the basin. It’s ideal if you’re tuning up for longer mountain hikes but still want to stay relatively close to home.
04
Best view-packed loop
Claremont Hills Wilderness Park Loop
Claremont Foothills • Popular Foothill Loop With Big Valley Views • Crowd-Pleaser For Weekend Group Hikes
A well-marked 5-mile loop that climbs steadily into the foothills above Claremont, with wide dirt roads, big views, and a social trail feel.
About 20 minutes from Diamond Bar, this is the go-to loop when you want a solid, predictable workout and a change of scenery. Expect a steady climb, a mix of sun and brief shade, and long views stretching from Mt. Baldy to the Inland Empire on clear days. It’s busy, especially on weekends, but the wide path makes it easy to hike at your own pace or bring a group.
05
Best nature escape
Carbon Canyon Nature Trail
Brea - Carbon Canyon Regional Park • Gentle Nature Walk With Coastal Redwoods And Wildlife • Best Mellow Escape On Warm Afternoons
An easy, mostly flat trail that trades steep climbs for shade, birdsong, and a surprising grove of redwoods just south of Diamond Bar.
Tucked inside Carbon Canyon Regional Park, this route is more about ambiance than elevation gain. The path winds past the lake and into a quiet canyon, ending in a small stand of redwoods that feels far from suburban Orange County. It’s a great choice for hot days, mixed-ability groups, or anyone who prefers a leisurely nature walk to a hard climb.
