The Waterfalls & River Rapids theme is a collection of fine art photographs featuring waterfalls and close-ups of river rapids with rocks. They are often part of a vast (mountain) landscape. However, some of the photos are more intimate and minimalist close-ups. These solely focus on the mystic beauty of the falls and rapids itself.

The theme includes photographs from around the world. Some are of famous locations, like the Skógafoss waterfall in Iceland and the Verzasca valley river in the Swiss Canton of Ticino. The photographs in this theme often use longer exposure times. As a result, the water looks smoother, and the resulting photo more pleasing.
