The path starts from the James A. Kell Visitor Center parking lot. This challenging walk starts with a fairly steep climb that winds through hardwoods to ridgetop conifers. Keen-eyed hikers can find remnants of an old springhouse and homestead by large hemlock trees. Wildflower enthusiasts enjoy this trail in the early spring to find the forest floor littered with trilliums, delicate ephemeral flowers that bloom before the first leaves begin to come in. Two short trails bisect the 1.8-mile loop offering hikers an opportunity for a shorter hike.
