A swimming-hole cascade over 1.5-billion-year-old rhyolite in the Missouri Ozarks.
Rocky Falls is a cascade in Ozark National Scenic Riverways where Rocky Creek pours over a broad outcrop of rhyolite porphyry, a hard volcanic rock the National Park Service dates to roughly 1.5 billion years old. The resistant rock pinches the stream into a narrow "shut-in" before the valley widens again downstream and the current spreads into a deep pool, the swimming hole that makes this one of the park's most visited stops. The Park Service notes that a true cascading waterfall is an unusual sight in the Ozarks, where most streams are spring-fed riffles rather than falls over rock.
The site sits off State Highway NN near Winona and has a developed day-use area with parking, picnic tables, grills, an information kiosk, a trailhead with hiker register, vault toilets, and wheelchair-accessible restrooms. No entrance pass is required anywhere in Ozark National Scenic Riverways, including here. The Park Service describes Rocky Falls as "a popular swimming hole in spring and summer," so expect company on warm-weather weekends, and check the park's river-level and conditions pages before visiting, since flow and footing at the shut-in change with rainfall.
