You can park at the trail's eastern end along San Vicente Boulevard. You can also access the trail from Los Alamitos Creek Trail.
I parked on Harry Rd and walked toward Santa Teresa Park. The trail was flat, easy, and pleasant, but became untenable in the exposed section that diverged from the creek itself. Granted, it was the late afternoon in June, but it was so scorching that we had to turn back. Would try again in the early morning fall/spring, or in winter.
