Vernal Falls is a short hike above the Valley, from the trailhead at Happy Isles. Often the majesty of a waterfall overwhelms the beautiful and subtle things that are happening at the edges. If you take a binocular with you, a whole new world of the waterfall opens up as you key on small sections. It's like watching a slow-motion movie, and mesmerizing. A telephoto lens can capture a moment of the ever-changing intricacy.
