When thinking of secluded canyons formed millions of years ago, Indiana isn’t usually the first place that comes to mind. Yet within Turkey Run State Park lies Rocky Hollow Falls Canyon, a naturally formed sandstone gorge carved 300-600 million years ago by erosion and glacial meltwaters. Venture across a nearly century-old suspension bridge spanning Sugar Creek, then down into the woods to explore narrow canyons, waterfalls, and striking sandstone cliffs.
The park’s cliffs reveal Mansfield sandstone, coal seams, and occasional fossil fragments of ancient marine life, while glacial erratics scattered along the trails hint at the region’s icy past. A ladder climb beside a seasonal waterfall and features like the Devil’s Ice Box and the Punch Bowl add adventure to the journey. Along the way, wildlife ranging from deer to copperhead snakes, and rare plants like ferns and hemlocks, remind visitors of the park’s rich ecosystem.
The Lusk Home and Mill Site, dating back to 1841, offers a glimpse of early settler life, while the name “Turkey Run” reflects the tradition of wild turkeys seeking shelter in canyon bottoms. To follow the main canyon trail, look for wooden markers for Trail #3 just after crossing the suspension bridge.
Beyond the canyon, Turkey Run State Park is a year-round destination for camping, swimming, canoeing, horseback riding, fishing, historical exploration, and connecting with Indiana’s natural history.
