I parked at the Biddle Street Trail Head parking lot located a block or two from Laclede's Landing. The lot, which accommodated about a dozen vehicles, was free and open to the public. From there, I walked north along the St. Louis Riverfront Trail for several miles before turning around to walk back. The trail follows the river's food wall through a heavy industrial area for about a dozen miles. During my walk I saw very few others on the trail.
