This well-maintained hiking and biking trail extends nearly 8 miles around and over Sugar Hill, the large ridge north of Oxbow Lake Park. The trail climbs steeply to the ridge and then curves back around near the dam at the eastern end of Oxbow lake. The Lower River Trail traverses the banks of the State Scenic Clinch River. This river is home to several species of endangered freshwater mussels. Feel free to observe them from the bank. Sugar Hill Loop Trail traverses dense hardwood forest filled with excitement for the patient observer. The trees hold numerous breeding songbirds including red-eyed vireo, wood thrush, yellow-billed cuckoo, and some warblers as well as fox squirrel.
The Sugar Hill and Clinch River Trails have been nominated as state birding and wildlife viewing trails because of the wide variety of flora and fauna found along the way.
The trailhead for the Sugar Hill Loop Trail is located just west of the Oxbow Lake Loop Trail. Parking is available at the Oxbow Lake Park (shared parking lot) or at the west end of the lake.
