Bring water and a tool kit. Sections of this trail are very isolated, don't expect cell service or other riders to ask for help.
The trail can be accessed on the south end from Hickory Ridge Trail or Deerfly Trails, in the middle from County M, and at the north end from County E. There are some less-travelled ATV turn-offs but the correct route is fairly well-signed.
From the south, the first major milestone is an enormous red boulder. This milestone will not go unnoticed and is the namesake of the trail for local MTBers. After this, the trail crosses County M. A few miles later, you come to a group of yellow trees near an intersection in the trail. The signage at this intersection can be easily missed. If so, remember to turn right (if coming from the south) at the yellow trees. Turn left here if coming from the north.
