While we were exploring this area, we spotted this small thoroughfare. After a small cardio session walking up and down the steps, we found a cool spot and came back the next day to hide a cache. The best parking is at the parking waypoint on Main Road.
You are looking for a small-sized container, there is no need to leave the concrete while searching for the cache. If your GPS is bouncing around while down at the cache, you will be at the right level if you'd descended 8 flights or ascended 3 flights of steps....
