Johnson's Shut-Ins State Park
River · Missouri
About this swimming hole
Johnson's Shut-Ins is Missouri's most famous natural water park, where the East Fork of the Black River squeezes through 1.5-billion-year-old volcanic rock. Centuries of erosion have worn the rhyolite into natural slides, chutes, and swirling pools that swimmers ride when water levels are safe. Swimming is allowed at your own risk, and weekend parking limits mean arriving early in summer.
