Beautiful pond for relaxing and taking in Spring or Fall seasons. Part of the Appalachian Trail.
At the end of the parking lot, cross over the bridge and follow the Appalachian Trail (AT, white blazes) to a V-intersection. Turn right onto Dunnfield Creek Trail (green blazes), which will take you past a few cascades and up to Sunfish Pond.
Relax and eat lunch at the pond. When you're ready, take the AT back to the parking lot, following the white blazes.
