Nestled in the western Puente Hills, Dark Canyon is a pleasant surprise, providing a true escape from reality just a short distance from the 605 Freeway. While the shaded confines of Dark Canyon make for good warm-day hiking destination, on cool days ambitious hikers can ascend the Switchbacks Trail and continue farther into the Whittier/Turnbull Canyon trail system.
From the dirt parking area, follow the signed trail across a service road and follow a dirt road into Sycamore Canyon. The early goings aren’t particularly attractive as you pass a water treatment facility and still hear noise from Workman Mill Road, but before long you’re engulfed in the attractive rolling terrain of the Puente Hills. Sycamore Canyon lives up to its name with numerous sycamores among the vegetation, along with oaks, chaparral, cacti and a few wild palms.
At 1.3 miles from the start, you reach a junction with the Switchbacks Trail, which climbs 400 feet in 0.6 mile to the ridge on the south wall of the canyon. The short but scenic Dark Canyon trail continues straight ahead. The trail hugs the side of the oak-shaded canyon, paralleling a seasonal stream. Keep an eye out for poison oak, which grows even in the exposed areas. In 0.4 mile from the junction (1.7 miles from the start) you reach the preserve boundary where you can sit beneath the oaks and enjoy the serenity before retracing your steps.
