Getting there

Chain of Rocks sits about 1.1 miles east of Glasgow Village in St. Louis (city) County. Navigate to the coordinates 38.75917, -90.17917, which mark the waterfall itself; the trailhead or parking area may be some distance away.

Open directions in Google Maps or Apple Maps, or view the map on the Chain of Rocks listing. Navigation apps sometimes route onto seasonal forest roads, so check road status if you are heading into the mountains.

Missouri's top falls are on public land: Rocky Falls is part of the Ozark National Scenic Riverways, managed by the National Park Service, and Mina Sauk Falls is in Taum Sauk Mountain State Park. Other sites are in city or county parks or near private land, so confirm access before visiting smaller falls. Ozark roads are often narrow, winding and gravel in places, and low-water crossings can flood quickly during storms. The trail to Mina Sauk Falls is rocky and uneven. Hazards include slick volcanic rock at Rocky Falls, sudden rises in small streams after thunderstorms, ticks and chiggers in warm weather, and summer heat. Swimming holes are popular, but water depth and currents can change after rain.

What to bring

This checklist is tailored to Chain of Rocks based on what visitors report and the conditions typical of Missouri. For the complete list, see our waterfall hike packing guide.

• Offline map and coordinates. Save 38.75917, -90.17917 and download offline maps; cell service is often weak near waterfalls.
• Shoes with real grip. Rock near falling water stays wet and slick even in dry weather.
• Water and a snack. More than you think you need, even for a short walk.
• A light rain layer. Spray from the falls and quick-moving showers can soak you.
• Headlamp. In case your visit runs later than planned; check sunset time in the conditions panel above.

How to prepare

Timing

Spring is the most dependable season for Missouri waterfalls, typically from March through early June, when frequent storms keep Ozark streams running. Mina Sauk Falls in particular is strongly seasonal and may be little more than a trickle in dry periods, so visiting within a few days of heavy rain makes a real difference. Summer is hot and humid; Rocky Falls draws crowds of swimmers in July and August even when flow is modest. Late summer and early fall are typically the driest stretch. Fall foliage in the Ozarks usually peaks around mid to late October and can be paired with autumn rains. Winter is generally mild in the southern part of the state, and occasional freezes can coat rocks with ice, adding hazard to steep trails.

Safety

Stay behind railings and off wet rock, never climb on the falls, and keep children within arm's reach near the water. Check the weather panel above for flood or storm alerts before you set out; water levels can rise fast after upstream rain. Our waterfall safety guide covers the most common hazards.

Respect the place

Pack out everything you bring, stay on established paths to limit erosion, and leave rocks and plants where they are. See Leave No Trace at waterfalls.

History of the area

According to the U.S. Geological Survey's naming record: In 1868 City engineer Homer erected a dyke from the Chain of Rocks, extending it out into the river.

Older maps and records also list it as Homer Dyke.

The federal gazetteer describes it this way: A natural bed of rocks, extending from the Missouri shore of the Mississippi River to a distance of about 1,600 feet.

Chain of Rocks was entered in the Geographic Names Information System on March 1, 1991, and it appears on the USGS Columbia Bottom 7.5-minute topographic map.

Its neighbors on the map tell the story of the surrounding land: Watkins Creek (stream, 1.0 mi).

Northern River Country. North and east of the Ozarks, Missouri's falls are linked to its great rivers. Rochester Falls in Andrew County, in the state's northwest corner, is a small fall and one of the very few in this glaciated part of Missouri. In St. Louis, USGS records the Chain of Rocks, a natural bed of rock that extends some 1,600 feet from the Missouri shore of the Mississippi River and once created hazardous rapids for river traffic. These sites show how rare natural drops are outside the Ozark uplands.
