Forty-five minutes from downtown St. Louis, one of Missouri's newest state parks hides a landscape you'd normally expect much deeper in the Ozarks: sandstone box canyons with 40- to 50-foot bluffs, seasonal waterfalls and shady oak-hickory woodland. Don Robinson State Park, in Cedar Hill, Jefferson County, opened in 2017 on land donated by a local businessman who made his fortune selling the heavy-duty cleaner Off. It's stayed under the radar compared with busier spots like Castlewood State Park, which is exactly the appeal.
The park packs more than six miles of trail into a compact area. The headline hike is the 3.9-mile Sandstone Canyon Trail loop — nearly 6,000 AllTrails reviews and counting — which threads along cliff tops and past several waterfall viewpoints. Trail staff suggest allowing three hours, and it's a genuine workout. Go after heavy spring rain if waterfalls are the goal; in a dry autumn, the falls often vanish entirely. Shorter on time? The 2.4-mile LaBarque Hills Trail takes around 1 hour 45 minutes through shaded woods to the park's high point, with ridge views that hold up well even without tall cliffs. Both loops have steep drop-offs, so keep well back from edges.
Autumn is the park's showpiece season. Cedars and Chinquapin oaks ignite into reds and golds, and unlike Castlewood, you won't be jostling crowds. Even non-hikers get a look: a viewing platform beside the main parking area sits above a panorama of forested gorges, complete with permanent Adirondack chairs, picnic shelters and grills. The shelter can be reserved for groups of up to 100. In deep winter, the waterfalls sometimes freeze into icy curtains against the sandstone — a solid reason to visit in the cold months too.
Practicalities are simple. Entry is free, the park is open year-round from 7 a.m. until half an hour after sunset, and parking is generous though weekends fill early. There's no regular camping here — only special-use sites for non-profits — so overnighters can drive 15 minutes to Robertsville State Park for standard tent and electric sites. Sitting just off I-44, the park also slots neatly into a road trip between St. Louis and Springfield, Missouri.
For city dwellers craving a half-day of solitude, leaf-peepers after an easy payoff, or hikers who want canyon scenery without the Ozarks drive, Don Robinson is a low-effort, high-reward detour from the Gateway Arch crowds.
