Sycamore Canyon Park is a 75-acre municipal park and canyon nature preserve located at 22930 Golden Springs Drive in Diamond Bar, California. Situated in the eastern San Gabriel Valley along the oak- and sycamore-shaded folds of the Puente-Chino Hills corridor, this public recreation area combines a developed lower community park with a rugged 1.4-mile natural canyon trail that follows a seasonal creek bed. Maintained by the City of Diamond Bar Parks and Recreation Department, the park attracts hikers, families, dog walkers, and nature lovers seeking shaded riparian trails, outdoor fitness equipment, and picnic facilities just minutes from State Route 60 and State Route 57.
What to Expect at Sycamore Canyon Park
Sycamore Canyon Park is divided into two distinct zones: a manicured, family-oriented front park near the Golden Springs Drive entrance and a natural riparian canyon extending northward toward the Temple Avenue trailhead. Near the lower parking lot, visitors find expansive grassy lawns, a shaded children’s playground with climbing structures and slides, outdoor fitness stations, a half-court basketball area, and covered picnic tables with built-in barbecue grills. Mature California sycamores and coast live oaks arch over the paved walkways, providing substantial shade even during warm Southern California afternoons.
Beyond the developed recreation area, the Sycamore Canyon Trail transitions into a dirt and crushed-granite singletrack and fire road that winds approximately 1.4 miles one way (2.8 miles round trip) through the canyon floor. Following a seasonal stream that runs with water after winter and spring rains, the trail crosses several rustic wooden footbridges and passes through dense coastal sage scrub and native walnut groves. The elevation gain is gentle—roughly 250 feet from the Golden Springs Drive entrance up to the northern trailhead near Temple Avenue and Campus Drive—making it suitable for beginners, trail runners, and children, though hikers should watch for exposed tree roots and occasional poison oak along the creek banks.

Visiting Tips, Getting There & Nearby Pairings
To secure a spot in the main parking lot at 22930 Golden Springs Drive—which holds roughly 35 vehicles and fills quickly on weekends—arrive before 8:30 AM. If the main lot is full, hikers can also access the northern end of the trail via street parking near the intersection of Temple Avenue and Campus Drive near Cal Poly Pomona, though parking restrictions should be checked carefully on surrounding residential streets. Public transit riders can reach the park via Foothill Transit Line 286 along Diamond Bar Boulevard or Line 190 along Temple Avenue. Dogs are welcome in the park and on the trail provided they remain on a leash no longer than six feet at all times.
The lower park area around the parking lot, restrooms, picnic shelters, and playground features flat, paved walkways that are step-free and accessible for wheelchairs and strollers. However, once you pass onto the unpaved Sycamore Canyon Trail, the path narrows and includes uneven dirt, tree roots, rocks, and creek beds that are not suitable for standard wheelchairs or narrow-wheeled strollers. After your hike, drive five minutes south along Diamond Bar Boulevard or Grand Avenue to find numerous Taiwanese bakeries, boba tea shops, and casual Korean and Chinese restaurants, or pair your outing with a visit to nearby Summitridge Park and Pantera Park.
