Park Avenue is an area of the park that runs N/S and is bordered by significant walls, formations, and towers on both sides - most notably Argon Tower at the North end. A trail runs between the canyon walls on slickrock from a pullout at the South end to the Courthouse Parking area on the North end.
Most routes are approached via Courthouse Parking (walk across the street to a well-cairned and worn trail).
