The Black Diamond Trail is an 8.4-mile stone-dust trail near Taughannock Falls State Park in the Finger Lakes. It is open year-round from dawn to dusk for walking, biking, snowshoeing and cross-country skiing. Hunting is allowed in season in places, so users are asked to wear blaze orange clothing during hunting season. There is no fee to use the trail, though a park use fee may apply when parking at Allan H. Treman or Taughannock Falls State Parks.
