Because of our notorious poor luck with weather, when we go hiking we always bring rain gear, extra layers of warm clothing and water-resistant packs. When most people see clouds like these, they sensibly stay off the trails until the threat of rain passes. For us, this is pretty good. With a little luck you can get holes between the clouds to put light onto your landscapes in pleasing patterns. The frame below allows you to zoom into this picture, can you find the two hikers climbing the peak?
