Carroll Homestead Interpretive Trail is an easy out-and-back from the main parking lot to the farmhouse, about 0.06 mile round trip on the wooded path. The mapped corridor is about 150 feet one way; the distance includes walking back. Think of it as a brief history stop, not a substantial hike. Allow about 30 minutes for the path and grounds, and longer if a seasonal ranger tour is running.
Available distance figures are longer and don't explain whether they include the driveway, return, or time wandering around the grounds. This figure covers the wooded walk and its return; it leaves out the separate gravel drive to the closer accessible parking area.
