Most climb discussions center around climbing. Depending on the day and time of year, Diablo presents both climbing and descending challenges as well as wind. The first time I did the south approach, it was colder. The top of the mountain was very cold. Climbing was okay but descending was horrible. My hands and feet were really cold and I would shiver to the point I had to stop to get warm. And there are some technical sections. If the weather is nice, it is great both up and down.
