Trailheads for both the Juanita Cooke Greenbelt & Bud Turner Trails can be found at the same GPS coordinates N33.91010 W117.93399 elev 351’ with street parking on Lakeside Dr.
North from W Hermosa Dr. to the W Las Palmas Dr overpass, the trail is covered with bark mulch, then dirt as it descends for about ½ mile to north end where a flood control ditch cuts the trail. The view expands here over the valley to the tops of the San Gabriel Mountains, or lower to Graffiti on the back of the apartment carports.
The trail is much more Hoof friendly then wheel friendly, it has more mulch than some gardens. The dirt portion is rough with scattered gravel. The steep, rough grade south out of the W Bastanchury Rd crossing required me to turn around at that point from both directions.
The South Trailhead has parking in the North County Municipal Court lot at N33.87948 W117.92570 elev 209’. Going North at the first street crossing, W Valley View Dr., the curb is not cut, turn left up hill to a private drive. the other curb is cut at the trail. Only the Street crossing at N Richman Ave & W Hermosa Dr. has cut curbs on both sides.
Even with these detractors I enjoyed the trails ambience and conservations with the hoofers.

"This trail follows the route of an abandoned railroad spur, so the grades and curves are gentle. I rode my mountain bike along the entire length of the trail in both directions. It is a good ride. Single tracks running parallel to the old roadbed in some places provide a more interesting ride for skilled bikers.

The trail is shown on the 2003 Thomas Street Guide on page 738.

The central portion of the trail runs along Morelia Ave. If you don't know that, you might have trouble following the trail.

A plaque posted at W. Valley View Dr. gives the history of the trail. Also posted at this location is the route of a 12-mile mountain bike ride around Fullerton.

Another trail through Hiltscher Park to Euclid Street makes a good side trip.

Although north end of the official trail may be at Hermosa Dr. near Laguna Lake, the path actually continues north until it is interrupted by the Coyote Creek channel. A rough informal path goes as far north as Imperial Highway, where the railroad spur still exists and there is a signalized grade crossing."
