Turkey Run & Shades — Sandstone Box Canyons on Sugar Creek
An hour and a half west of Indianapolis, Sugar Creek has spent millennia carving the flat Illinoian till plain into a hidden world of deep sandstone canyons, ferny gorges, and cool hemlock ravines that feel utterly out of place in the corn-and-soybean country around them. Turkey Run State Park is the headline act: a network of ladder trails that drop hikers down slot canyons, over creek boulders, and beside seasonal waterfalls, with the celebrated Trail 3 threading the narrowest and most dramatic of the gorges. Just upstream, Shades State Park is Turkey Run's quieter, wilder sibling — steeper, rougher, and lightly developed, where ladder-and-handrail descents like Devil's Punchbowl and Silver Cascade reward the surefooted. This is one long, physical day of scrambling, wading, and canyon-bottom hiking, capped by a hearty meal in Rockville or Crawfordsville before the drive home.
