If you're taking I-10, take Exit 34 (Americas Ave / Loop 375) and drive southwest toward Zaragoza Bridge. When the Loop 375 turns freeway, look out for the exit for Alameda Ave and Pan American Drive (and some others). Take this exit into the frontage road and turn left on Pan American Drive. You'll cross a bridge over the Playa Drain and another over the Riverside Canal. Turn left on the levee road and look for the park.
