Chasm Falls is a 25-foot waterfall on the Fall River in Rocky Mountain National Park and one of the park’s notable named cascades. Better known for alpine lakes, peaks, and sweeping mountain scenery, the park also includes this distinct river feature, where water drops a short but clear 25 feet through a narrow rocky channel. As part of the park’s high-country river landscape, Chasm Falls helps shape the terrain and adds to the appeal of the park’s streams alongside its better-known mountain vistas.
