The Black Trail is the newest addition at Ontario County Park. It occupies a lower bench on the east side of the park and adds approximately four miles and 600 feet of elevation change to the network.
The Black Trail has a few options for looping, the most interesting of which is a figure-8, running the north half clockwise and the southern loop counter-clockwise. Doing so earns you a full mile and 370 vertical feet of descent, a rarity in the Genesee Valley region. The climb out has some steep moments but is well-built and manageable for most.
