The person who built these stairs did a really good job, there are so many people running up and down each day and the wood is still in pretty good shape!
The stairs are mainly used for exercising. You see young people, older ones, fit ones, not so fit ones and dogs as well. They all run or walk up and down, breathing heavy. I do it myself and every time I run up I feel like my lungs explode. But at the top you get rewarded with such a beautiful view of the city, with the mountains in the back! There are a few benches at the top, really nice to sit down and enjoy the view. Went their ones to see the sunset on a warm day and a guy was playing his guitar.. it was like the wipped cream on a cake.
Try parking at the top, it's free, but only for a short time.
