5 /5 Kenneth Lonas: A wonderful collection of trails for hiking and mountain biking. At some areas it is a bit rocky and should be approached with caution. In my inattention, I have crashed here and left some blood, but it was my inexperience and certainly not the trail. In addition, OSI, Open Space Institute, has recently purchased (2019) a large tract of land adjacent to the Bluestone Forest and will be building more trails to the east. Hopefully there will be a connection to the nearby Jockey Hill trails.
