The Black Diamond Trail is an 8.4 mile stretch of stone dust trail, which has been converted from an old railroad bed. The trail passes through a mix of woodland and pastoral lands along the western slope of Cayuga Lake. Trailheads at Cass Park/Allan H. Treman State Park in the City of Ithaca and Taughannock Falls State Park in Trumansburg provide parking and access to the trail. Recreational opportunities include hiking, jogging, biking, snowshoeing and cross-country skiing.
Household pets only on a leash, not more than 6 feet. Certificate proof of rabies inoculation. Please curb your dog.
The trail is open year round from dawn to dusk.
Most New York State Parks charge a vehicle use fee to enter the facility. Fees vary by location and season. There is no fee to use the Black Diamond Trail; however, a park use fee may be encountered if accessing the trail from parking available at Allan H. Treman and Taughannock Falls State Parks.
Highlights of the Black Diamond Trail:
Hunting and trapping are prohibited along the trail. However, private property adjoins the trail corridor where hunting may occur during hunting season. NYS Parks recommends wearing an article of blaze orange clothing for added safety during hunting season.
