This is at Black Hill Regional Park (Shelter F). I tried this a few weeks ago and only made it up halfway. I decided to try it again today. I actually made it to the top but had to take my foot off right at top. You can't see it from the video but the stairs consist of two steps, then a small platform, then another two steps, and so on. It took about 20 tries before I could make it. It was fun!
