My husband and I hiked the trail over Labor Day weekend. We arrived around 8:45. There were still plenty of parking places, whereas the day before at 2:30 there weren't any. We are competitive and like to good challenge. Our time to the top was 31 minutes. I can definitely see how some people find it challenging. It all depends on your fitness level. I saw people from two years to around 75-80, some fit and some were struggling to catch their breath. It is absolutely breathtaking and I am so glad we went back a second day to try to find a parking spot. Some of the most beautiful views in the world!
