Deukmejian Wilderness Park

Natural Landscape

Set in the foothills of the San Gabriel Mountains, Deukmejian Wilderness Park sprawls across 709 acres at Glendale's northernmost edge. The terrain here is a captivating blend of chaparral and sage scrub, with hidden streamside woodlands tucked away in the folds of Dunsmore and Cook's Canyons. There are even scattered remnants of big-cone spruce woodland if you know where to look.

Rising from about 2,159 feet at the entrance to an impressive 4,775 feet in the northeast corner, your climb is rewarded with expansive views of the Crescenta Valley and the Los Angeles basin below. In spring, wildflowers dot the hills with splashes of color, making it an especially nice season to visit.

Trail System

The park's network of trails winds through rugged terrain, where you might discover natural features and catch glimpses of local wildlife. These paths don't just end at the park boundaries - they seamlessly connect with the surrounding wilderness.

With the Angeles National Forest bordering three sides (north, west, and east), Deukmejian connects naturally to the larger wilderness area.

You'll find 10 distinct trails here, each with its own personality and challenge level. Whether you're looking for an easy walk or a challenging hike, options range from the gentle Le Mesnager Loop to the more difficult Rim of the Valley. Other options include Dunsmore Canyon, Vineyard, Mummy Rock, Crescenta View, Cook's Canyon, Haines Canyon, Mt Lukens, and Pickens Spur.

The Dunsmore Canyon Trail stretches about a mile with a 600-foot elevation gain over rocky terrain. For those seeking a more ambitious adventure, the trail to Mt Lukens summit offers remarkable panoramic views - but plan accordingly, as it's at least a 6-hour journey that requires proper preparation.

Park Center

The southern portion of the property features a more developed 12-acre Park Center area. Here you'll come across the historic Stone Barn Nature Center (originally the Le Mesnager Barn), the Glendale Park Ranger Station, parking, restrooms, and several pleasant picnic spots.

Open on weekends, the Stone Barn Nature Center functions as an educational hub where you can learn about local ecology, geology, and regional history. Its interactive exhibits teach visitors about the surrounding environment, plant life, and wildlife, as well as the people who have called this area home throughout history.

Behind the Stone Barn sits a small vineyard - a thoughtful nod to the property's past.

Recreation Areas

Throughout the grounds, you'll discover well-maintained picnic areas with tables placed in both shady and sunny spots. The grassy sections offer especially nice views of the Crescenta Valley below - fantastic for family gatherings or a peaceful solo lunch.

A cozy outdoor amphitheater tucked among the trees hosts community events and educational programs. The city occasionally organizes nature activities and guided hikes, which are particularly great for families with children.

As you explore, you might encounter rabbits, lizards, various birds, and sometimes coyotes or snakes. The park takes on a particular beauty after winter storms, when seasonal streams come alive in the canyons and snow occasionally dusts the higher elevations.

Park Boundaries

The southern edge of the park is primarily taken up by a County debris basin and sediment placement site, also known as a spreading ground.

Visitor Information

Parking is free, but spaces can fill quickly on weekends. Clean restrooms and water fountains are available near the entrance. Dogs are welcome throughout the park but must remain on leash at all times.

Note that due to the wilderness setting, cell service can be spotty or nonexistent in parts of the park. If you're planning a longer hike, come prepared with water, snacks, and appropriate gear - especially important during the hot summer months.
