More for people walking dogs than for bikes. Mostly doubletrack, some small but steep climbs/downhills. Don't think I saw one rock, very few roots. A place to stretch the legs if you're around, not somewhere to travel to. Good place for beginners to get comfortable.
From I-87, take exit 10. Go west towards Jonesville, take first left after the highway onto Pierce Rd. Follow until the end, take a right onto Kinns Road. Parking is in a lot with a sign and will be on left a few miles down.
